Abstract
Abstract A plasticizing composition for polyvinyl chloride resin is prepared by mixing from about 20 to about 50 parts by weight of tris(alkoxyalkyl)phosphate having the formula ##STR1## wherein R 1 , R 2 and R 3 are alkoxyalkyl radicals having the formula: ##STR2## wherein n is an integer from 1 to 18; x is an integer from 1 to 2; R' is either hydrogen or an alkyl radical, and R" is either hydrogen or an alkyl radical; in combination with from about 80 to about 50 parts by weight of another phosphate ester selected from the group consisting triaryl phosphate, alkyl diphenyl phosphate, trialkyl phosphate, tris(alkylphenyl)phosphate, alkylphenyl/phenyl phosphate, and mixture thereof. Polyvinyl chloride resins plasticized with 30 or more parts per hundred of such phosphate ester plasticizer mixtures are heat stable, fire resistant and flexible at low temperatures.
