Vinyl chloride polymers plasticized with morpholides of the fatty acid constituent of cottonseed oil

Claim 1

A PLASTIC COMPOSITION WHICH IS STABLE AGAINST EXUDATION OF PLASTICIZER COMPRISING A MIXTURE CONTAINING A VINYL CHLORIDE POLYMER SELECTED FROM THE GROUP CONSISTING OF POLYVINYL CHLORIDE AND A VINYL CHLORIDE-VINYL ACETATE COPOLYMER WHICH CONTAINS A PREDOMINANT AMOUNT OF VINYL CHLORIDE, AND A PLASTICIZER THEREFOR COMPRISING A MORPHOLIDE MIXTURE OF MORPHOLIDES OF SELECTIVELY HYDROGENATED COTTONSEED OIL FATTY ACIDS, THE SELECTIVE HYDROGENATION BEING PERFORMED UNDER CONDITIONS WHICH RESULT IN REDUCING THE PROPORTION OF POLYOLEFINIC ACYLS IN THE MIXTURE BY CONVERTING THE POLYOLEFINIC ACYLS TO MONOOLEFINIC ACYLS WITHOUT SUBSTANTIALLY INCREASING THE PROPORTION OF SATURATED ACYLS IN THE MIXTURE, SAID MORPHOLIDE MIXTURE CONSISTING OF THE MORPHOLIDES OF MONOOLEFINIC FATTY ACIDS (M), POLYOLEFINIC FATTY ACIDS (P), AND SATURATED FATTY ACIDS (SE, SAID SATURATED FATTY ACIDS (S) BEING PRESENT IN THE AMOUNTS NATURALLY OCCURRING IN COTTONSEED OIL, AND IN WHICH MORPHOLIDE MIXTURE THE PROPORTION OF THE POLYOLEFINIC FATTY ACYLS BASED ON THE TOTAL UNSATURATED ACYLS IS SUCH THAT
