Zusammenfassung:	1,162,603. Polyvinyichloride compositions. JOHNSON & JOHNSON. 12 April, 1967 [21 April, 1966], No. 16729/67. Heading C3P. Compositions for making mouldable orthopaedic splints comprise a vinyl chloride-vinyl acetate copolymer, 5-25% by wt. based on copolymer and solid plasticizer of a monomeric solid plasticizer and 2-6 parts per 100 parts by wt. of copolymer of a liquid epoxidized olefinic oil having an iodine value of 120-135 prior to epoxidation and of 1-5-6 after epoxidation. The preferred plasticizer is triphenyl phosphate or dicyclohexyl phthalate and the epoxidized oil may be epoxidized soybean oil. Optionally an acrylic polymer may also be added.
