SUMMARY: 1- SPI will obtain an opinion from Keller & Heclanan concerning the implications of collecting and sharing toxicological information. 2- Prior to establishing an Additives Committee, contact will be made with the Chemical Specialities Manufacturers Association and SPI member companies who are both resin and additive suppliers as to the best way of gathering data on additives. 3 - Members companies are to review the reproposed TSCA reporting regulations to determine if a Plastics Industry response is needed separate from other chemical industry responses.

There was a concern expressed at each subcommittee meeting about sharing of unpublished data, location of the "data bank", accessability to the "data bank" and the implications of establishing a "data bank". These issues also generated considerable discussion among the committee members. It was decided that SPI should obtain an opinion from counsel on these issues prior to the committee establishing guidelines for the subcommittee. 3- Each subcommittee also expressed the need for a unified effort to obtain toxicology data from suppliers of additives* Bather than establish an additives committee at this time I.A. Lundgaard, & J.R. Lawrence will discuss the problem with Wm. Considine at CIBA Geigy who showed great interest in our program at Washington and is also an additive supplier. Contact will also be made with the Chemical Specialities Manufacturers Association (CSMA) and SPI member companies who are both resin and additive suppliers. SPI will have counsel review a draft letter prepared by B. M. G. Zwicker requesting toxicology data from additive suppliers. 4- BMG Zwicker reported that the vinyls subcommittee had established a vinyl acetate task force. The task force will be holding its first meeting 7/20/77. It was determined that an SPI representative to present at all meetings, including technical meetings such as this. 5 - CUT will be contacted by SPI to determine their time schedule for propylene, vinyl acetate, formaldehyde and maleic anhydride. 6- Several subcommittee chairmen reported that subcommittee members thought SPI should be prepared to make a response to the new TSCA reporting rules. A need was also expressed for a unified nomenclature for reporting of multicomponent polymers. It was determined that all members review the new rules when they are issued and then contact SPI if they see a need for an industry response. 7- BMG Zwicker recommended Waveland D. Davis succeed Dr, Zwicker as chairman of the vinyls subcomnittee upon Dr. Zwicker*s retirement. The chairman approved the recommendation. Respectfully submitted HPT:md H. P.

Gorham, at 9:30 a.m, June 23 at the Marriott Twin Bridges Motel* Washington, D.C. After self-intro ductions, the minutes of the April' 17 meeting were distributed. Action by the Vinyls Subcommittee at their June 22 meeting regarding substances also of interest to this group were reported to be as follows: 1. Vinyl acetate--recommended fop further toxicity testing. 2. Ethylene and propylene--referred to this committee. 3. Peroxide catalysts -- referred to suppliers. A. PVC respirable particles--task force to study. The subcommittee reviewed in detail the June 15 Interim Report of Foster D. Snell, Chapter lll-A, Polyolefins, to be sure that all substances requiring further study are identified. These substances consist of fumes including acrolein, dust, peroxides, ethylene, propylene, vinyl acetate, butene, hexene, and chromium oxide catalysts. Low molecular weight hydrocarbons was added. The subcommittee also reviewed Chapter IV, Plastics Additives, to identify those critical substances used in polyolefins. There were as follows: Antioxidants Antistatic Agents Colorants Fi 1 lers and Fibres Flame Retardants U. V. Absorbers Crosslinking Agents Organic phosphites especially TNPP Thipesters (of less concern) Phenolic derivatives Amine type only Cadmium pigments Chromium and lead pigments Carbon black Phthalocyanines Titanium dioxide Iron oxides U1tramarine blue Molybdate orange Azo pigments Glass fibres Antimony oxide Dechloranes Nickel compounds Benzotriazoles Benzophenones Peroxides includi Dicup (B priority) The subcommittee then reviewed, classified, and discussed the current status of all substances identified as critical to polyolefin plastics. Action plans were agreed upon as follows: see 5-1652 2 Monomers Ethylene--A 2 year inhalation study is under way at CUT and information to date indicates there are no problems. This committee will monitor the study singe many member companies support CUT. No further action recommended. Propylene--Appears on second CUT list of candidate materials but there is no assurance work will be done in the near future, if at all. This committee will recommend that SPI contact CUT urging them to support toxicity studies and hopefully obtain some commitment with a timetable. Butene-1 and Hexene-1--These monomers are referred to our Toxicology Committee for literature surveys and review. Vinyl Acetate--This committee defers to the Vinyl Subcommittee .and supports their recommendation that additional toxicity studies be supported. Polymer Constituents Low Molecular Weight Fractions of Polymers--USI and UCC both have unpublished 90-day feeding studies in rats and dogs. These will be made available to the Toxicology Committee for critical review. Others are urged to submit any available information. Chromium Oxide Catalyst Residues--Phillips has 90 day feeding studies on chromium oxide catalyst residues which they will provide to the Toxicology Committee. UCC has extraction studies on HDPE resins in simulating food solvents which show migration at fractional ppb levels which will also be provided. The Toxicology Committee will review both to assess potential hazards. A catalyst manufacturer, Davison Chemical Co., will also be approached for toxicology. Peroxide Residues--Low priority with no recommendation at this time. Decomposition Products--Fumes have been studied by Dow, Phillips, UCC, and others. It was agreed that anyone having data will submit to W. B. Ackart {Union Carbide Corporation, River Road, Bound Brook, NJ 08805) who will summarize and report at the next meeting. Low molecular weight hydrocarbons and acrolein are assumed to be present in fumes. Dust is given a low priority because (1) resin particles are probably not of respirable size, and (2) are probably physiologica11 inert. Additives The formation of an Additives Committee Is under consideration by the parent Toxicology Strategy Committee. Dr. Gorham will report our interest in' the additives previously identified. If the Additives Committee then does not obtain adequate information on these substances of interest, this committee will consider contacting suppliers for information. see 5 -- 16 5 ~ 3 Consideration was then given to the formation of a Toxicology Subcommittee which has already been assigned the following tasks: 1. Butene-1 and Hexene-1--Literature survey and review followed by a recommendation for future action, 2. Low Molecular Weight Fractions of Olefin Polymers--Critica1 review of UCC and US I feeding studies. 3. Chromium Qxide Catalyst Residues--Review of Phillips feeding study and UCC extraction data and assessment of potential hazard. Potential members are Dr. Homan of UCC, Dr. McFarland of Gulf, Dr. Tyler of Phillips, and Dr. Sherman of DuPont. Dr. Hughes of Gulf suggested that the next meeting of the Polyoelfins Subcommittee be held in the Southwest where many members have facilities. It was agreed that a two day meeting would be scheduled with preliminary (optional) activities on Wednesday, September 28 and a wrap-up session on Thursday, September 29. Dr. Hughes will make suitable arrangements. The meeting was adjourned at about 2:bS p.m. WBA:j vm June 28, 1977 i j Q> W.' B. Ackart Secretary see 5-1654 ATTENDEES: Watson B.
