Bauer January 31, 1968 it SUBJECT: Vinyl Resin and Plasticizer Summary - Tarrytown Technical Center, January, 1968_ CALENDERING, FLOORING & RECORDS VINYL SUSPENSION RESINS FOR CALENDERING (333 S 90) 1. VINYL CHLORIDE-ETHYLENE COPOLYMERS - APPLICATIONS STUDY _____ The revised applications program relating to these copolymers will not be issued for another two weeks. Meanwhile, two phases of the program are underway. The use of type - III resins in calendered film and sheeting is reported under Vernon Plastics; the use of type - I in wire and cable is summarized under QSAN-7 in that section of this report. (W. H. Bauer) 2. PLATE-OUT STUDIES Rerun of the five resins outlined in the December Summary failed Reproducibility of -theFordplate-out test is a plague upon this program. A sample , of Borden's VC 106 PM (suspected to be acid polymerized) was somewhat lighter than QYTQ-7 (Blend 211). During February, a meeting will be held with Messrs. Richard son and Meissner to determine the future course of this study. (W. H. Bauer) 3. ELM COATED FABRICS, BROOKLYN, NEW YORK Hie customer has all but abandoned the use of Process 5 resins and all efforts to secure approval of Process 7 counterparts have met with failure. Mr. L. G.

COMPETITIVE MATERIALS The sample of Airco propylene modified PVC, 470, from Tenneco/ J. N. Barton has not been received and is presumed as lost in transit. (P. T. McCoy) PLASTICIZERS FOR CALENDERING (333 S 50) 1. PERMANENT (POLYMERIC) PLASTICIZERS The work done by many groups is beginning to come to fruition. The plant run on R3M is scheduled for mid-January. The production material will then be checked for performance in the various end-use areas. All applications data required for market introduction will be available two months after receipt of the plant sample. Evaluation of second generation permanent plasticizers will proceed concurrently. These materials include copolymers of caprolactone with ethylene oxide, propylene oxide and styrene oxide. A cursory look will be given to chlorinated poly ethylene as a plasticizer for PVC to obtain sufficient data to establish a probable im pact on the market. (W. H. Bauer, E. B. Harris) 2. PLASTIC CALENDERING CORPORATION, FARMINGDALE, NEW YORK Masland cold crack tests were completed on two different samples of flexible vinyl for this customer within 48 hours of receipt of samples. Customer requested work on an emergency basis. FLOORING, SUSPENSION VINYL RESINS (333 R 90) 1. RESINS FOR VINYL ASBESTOS TILE A factorial design layout for determining constants of a polynom ial response equation relating physical properties of vinyl asbestos tile stocks to compositional variables was investigated. The method proved satisfactory for objec tive rating of binder and plasticizer requirements of vinyl resins. The method will be used to compare vinyl chloride - vinyl acetate - ethylene terpolymers with standard VSJD-10. A control formula evaluation has been completed. Additional raw materials are now on hand to complete the comparative, study of experimental VXRF terpolymers. (R.P. Braddicks, Jr.) 2. COMMERCIAL FLOORING SAMPLES i* Commercial flooring samples have been solicited from producers' for a detailed study of product construction and design requirements. It is believed -that examination and study of these samples will improve our understanding of special customer needs. Requests, to date, have been received favorably. (R. P. Braddicks, Jr.) 3, TEST METHODS Modified test methods are being evaluated in an effort to derive more accurate stiffness values, tensile data and hardness readings for vinyl asbestos tile stocks. FLOORING PLASTICIZBRS (333 R 50) (R. P. Braddicks, Jr.) 1. EXTENDERS It was suggested that certain blend stocks of UCANE Alkylates and also of the n-parafflns used in their manufacture be investigated as possible " sources for extender-type plasticizers. The n-paraffins would be chlorinated to approximately 45-50 per cent chlorine content similar to "Cereclor" S-52. Dr. C. W. McGary has agreed to investigate these possibilities. . ,, (R. P.

NATIONAL FLOOR PRODUCTS, INC,, FLORENCE. ALABAMA This customer requested assistance in formulating vinyl shoe sole compounds to match properties of aim materials. Initiation of laboratory work is awaiting receipt of the aim samples. (L. G. Krauskopf) MOLDING & EXTRUSION (211 V 90, 211 V SO) 1. GENERAL ELECTRIC COMPANY, LOUISVILLE, KENTUCKY Typical formulations of vinyl gaskets for driers and washer tubs have been calculated by the computer formulating technique. These formulations have been provided to Mr. G. C. Shipston for purposes of assisting GE in a current make vs. buy study of vinyl components for appliances. (L. G. Krauskopf) 2. BROWN SHOE COMPANY, ST. LOUIS, MISSOURI The development of plasticized vinyl dry-blend compositions, based on QSOM-7 resin, for vinyl shoe soles is in progress. Aim material has a Durometer A of 58, (L, G. Krauskopf) 3. UNI-GRIP, INC., UPPER SANDUSKY, OHIO BAKELITE resin QYTQ-7, Blend 330 (<i% ethylene copolymer) was assessed in this company's dry-blending and extrusion operation, employing a Henschel mixer. Dry-blends utilizing Blend 330 were of borderline quality. A Report of Call describes the plant trial and suggests the following courses of action; / 1. Resubmit selected blends of dry-blend grade suspension resin when Uni-Grip, Inc. starts up their new processing line. This will be an improved L ip ucc 042155 6. layout making the consistency of the dry-blend less critical at the point of leaving the Henschel mixer. 2. Develop improved methods for laboratory measurement of dry-blending characteristics of suspension polymers. : (L. G. Krauskopf) % 4. GLOBE RUBBER PRODUCTS, PHILADELPHIA, PENNSYLVANIA Production of a continuous, clear, flexible vinyl runner has been unsatisfactory on this company's new extrusion line using dry-blends based on Borden VC 100 PM resin and FLEXOL plasticizers DOP and GPE: Observation of plant trials employing FLEXOL plasticizers 426 and 575 as partial replacements for DOP indicated that some improvement was achieved. However, shortage of material on hand jpre- . eluded the evaluation of higher levels of the more solvating plasticizers. Globe- Rubber plans to proceed with additional evaluations. jv'., - A brief evaluation of resin interchange indicated that QYTQ, Blend 330, (<1% ethylene copolymer) provided a similar dry-blend to Borden VC 100 PM, when dropped from the Henschel mixer at 10 to 15 degrees lower than normal operating temperature. However, it appears that optimization of formula (resin, plasticizer, lubricants, etc.) can only partially contribute toward an objective of raising extruder output to 900 pounds per hour. (L. G. Krauskopf) 5. GEAUGA PLASTICS COMPANY, CRESTLINE, OHIO This customer was provided with a typical 90 degree appliance wire formulation which is intended for use as a high temperature gasket for GE appliances. Also, suggested formulations for a general purpose, low cost vinyl were provided. The filled vinyl formulations were based on BAKELITE resin QSAM7 and FLEXOL plasticizers DOP and EPO and utilizing plasticizer extenders. %-r . *`**V -, (L. G. Krauskopf) 6.

This company has submitted samples of dry-blends from their manufacturing line for extruded, clear vinyl sheeting. The objective is to assess th effect of substituting FLEXOL plasticizer EPO for die currently used epoxy plastici zers (combination of Bpoxol 9-5 and "Admex" 746). Initiation of the project has been delayed for the following reasons: 1. Unclear definition of epoxy level employed (recently established) sentative. 2. No "Request for Technical Service" submitted by sales repre 3. Heavy demand for laboratory effort by other molding and . extrusion customers. It is estimated that Wiman Manufacturing consumes in excess of * eight MM pounds of vinyl resin and four MM pounds of plasticizer, approximately ,? 3/4 MM pounds of which is epoxy type. * (L. G. Krauskopf) 8. DRY-BLEND GRADE SUSPENSION PVC's A brief investigation of dry-blending characteristics of some Union Carbide and competitive resins has been useful toward observing die more obvious differences in certain dry-blend resins. It also has shown the need to develop tests to measure differences accurately. However, the proper and uninterrupted pursuit of a program of this nature is precluded by shortage of manpower. (L. G.

The pur pose of this study will be to attempt to make a valid assessment of QSAN-7, typeu- I, resin, prior to market introduction. V V; 'Vr*- \*j- ,, (E. B. Harris) ucc 042157 8. 2. COLEMAN CABLE AND WIRE COMPANY, RIVER GROVE, ILLINOIS Laboratory work has diown that, in Coleman's formulation, FLBXOL R3M equals S-409 in performance when tested against military (MIL-C-5086) and UL 105 wire insulation specification and that neither meet the requirement. However, when Flastanox 1161 is incorporated into FLEXOL R3M, it passes. Furthermore, QSAN-7 (Blend 89, homopolymer), which was included in the study for informational purposes, dry-blended faster than the experimental Dow resin (in the Henschel [high shear] mixer). The Brabender dry-blend evaluation (low shear) indicated the opposite in relative performance. . (B. B. Harris) 3.

HEWITT-ROBINS, BUFFALO, NEW YORK FLEXOL EPO was found to be marginally inferior to the currently used polyester plasticizer blend in rub-off resistance. At present, FLEXOL EPO is our only candidate for this application. A visit to Hewitt-Robins will be made to dis cuss this problem of conveyor belt coating failure during use. (E. B. Harris) 2. GROW CHEMICAL CORPORATION, DETROIT, MICHIGAN The writer visited Grow to discuss plate-out problems encountered in a foam plastisol used to package auto parts. Several suggestions on additives and resin interchange were discussed and will be evaluated by Grow. v (E. B. Harris) 3. TEXTILE RUBBER AND CHEMICALS COMPANY, DALTON, GEORGIA A project is underway to derive data on the fusion characteristics of RAKELITE QYLF as compared to "Geon" 135 and Opalon 440. Per L. A. McKenna's visit to Textile Rubber, QYLF had made a poor showing in an earlier evaluation by the plant chemist in a rotational molding application. Our objective to change QYLF's image and pave the way for future approval by Textile Rubber. (E. B. Harris) PLASTICIZER SYNTHESIS (ALLOCATED) The preparation of di-2-ethylhexyl-5-norbomene-2, 3-dicarboxylate was completed. A dark brown, dense liquid was obtained in 91 per cent yield. Reports - - ^ in the literature of decomposition upon attempted distillation of the compound precluded ' such procedure. As reported previously, the dibenzyl ester also underwent decomposition when subjected to vacuum distillation.. Attempts to decolorize the compound with activated charcoal were unsuccessful and it was decided to carry out the purification steps after addition to the double bond. Utilizing boron trifluoride as a catalyst it appears that the addition of V ^ acetic acid to the unsaturated diester proceeds successfully. By refluxing the reac- ' tants for two hours, a dark liquid is produced, in approximately 75 per cent yield, - V?- ^_ whose infra-red spectrum suggests the presence of a triester; in this case the - ~ .10 5'acetoxynorbornane-2, 3-dicarboxylate. However, further information is required before this structure may be assigned with certainty. In addition, a second liquid and a small amount of a high melting solid were obtained. These products are, as yet, unidentified. The liquid is fairly volatile and arises from attempted distillation of the product. Treatment of the non-volatile triester with activated charcoal produced no decoloration. However, passage of the compound through an alumina packed column gave a colorless liquid. Should further identification bear out the triester structure, this would represent die first example of this class of compounds, and would demonstrate the feasibility of preparing these compounds from relatively cheap raw materials by these procedures. Additional compound is now being prepared so that a sufficient sample may be available for evaluation as a plasticizer for PVC. Also, it is planned to carry out the addition reaction with higher homologues of acetic acid to determine the scope of the reaction. (S. Solomon) W.H.Bauer:ccb CUSTOMER CALL REPORT C.F. & R.
