Conkling Supervisor: W.H. Bauer Date: November 7, 1966 Project No: 224A90 File No: SUMMARY A comparison of the unfilled compound physical and processing characteristics of ethylene modified vinyl resins QSOM-7 Blend 3 and QXOM-7 QEX 1197 and a conventional homopolymer QYTQ-7 has been completed. The differences in ethylene levels: QYTQ-7 QXOM-7 QEX 1197 QSOM-7 Blend 3 0 percent 1.4 percent 0.9 percent shows that: 1. QEX 1197 (1.4 ethylene) requires 5 PHR (11 percent) less of FLEXOL plasticizer DOP than does QYTQ to achieve a Durometer A Hardness of 80; Blend 3 (0.9 ethylene) requires 2.5 fflR (5 percent) less. 2. The amounts of FLEXOL plasticizer DOP required to achieve constant melt characteristics are: QYTQ QEX 1197 Blend 3 - 40.5 PHR - 32 PHR - 38.5 PHR 3. The. 1.4 percent ethylene level for a QSOM type resin is thus recommended to provide a more unique product to the calendering and flooring fields than that offered by the 0.9 percent level.

DISCUSSION This study is designed to define the influences of both internal and external plasticization upon the ethylene modified version of OYTQ to assist in establishing product specifications. This report supplements previous findings that QSOM Blend 3 required a lesser amount of external plasticization to achieve the same physical properties of QYTQ. The sample preparation techniques of the previous investigation I1) were utilized in this study which was designed as slightly less intense than the previous evaluation. The data are shown in Table I and Figures 1 and 2. (1) A.W. Conkling and P.T.

Property Durometer A D Average Percentage Greater/Less Than QYTQ-7 QXOM-7 QSOM-7 QEX 1197 Blend 3 - 4 -2 - 21 - 8 Tensile - 6 -3 Elongation +3 +4 Apparent Melt Viscosity - 13 - 1 Fusion Time - 99 -73 The amount of plasticizer to obtain a Durometer A of 80 (plasticizer efficiency parameter) for these resins, follows: QYTQ-7 - 47 parts QXOM QEX 1197 - 42 parts QSOM Blend 3 - 44.5 parts This indicates that about 11 percent less plasticizer is required by QEX 1197 and about 5 percent less by Blend 3; QEX 1197 requires about 6 percent less than Blend 3. The amount of plasticizer required to obtain an apparent melt viscosity of 1,500 meter grams per second (Plasti Corder) for these resins follows: QYTQ - 40.5 parts QXOM QEX 1197 - 32 parts QSOM Blend 3 - 38.5 parts This indicates that QEX 1197 requires about 27 percent less plasticizer than QYTQ and that Blend 3 requires about 5 percent less; QEX 1197 requires about 22 percent less than Blend 3. ucc Q'394 8 8 - 3The higher fusion torques of QEX U97 as compared to QYTQ and Blend 3 are possibly related to differences in resin-plasticizer solvency characteristics.
