Abstract
The present invention relates to organic polymer compositions, containing liquid ester compositions as plastisizers, said compositions comprising mixtures of esters derived from (a) diethylene glycol and triethylene glycol and (b) benzoic or toluic acid, wherein the freezing point of the ester mixture is below the freezing points of the constituent esters when the relative concentrations of the constituent esters are within specified limits.
Claims16
An organic polymer composition comprising at least one thermoplastic organic polymer and an amount sufficient to plasticize said polymer of a liquid ester composition comprising
- 1) a first diester of the formula ArC(O) (OCH2CH2)2O(O) CAr and
- 2) a second diester of the formula ArC(O) (OCH2CH2)3O(0) CAr;
- wherein Ar represents a phenyl or methylphenyl radical, and the freezing point of said composition is below the freezing points of said first and second diesters.
An organic polymer composition comprising at least one thermoplastic organic polymer and an amount sufficient to plasticize said polymer of a liquid ester composition comprising
- 1) a first diester of the formula ArC(O) (OCH2CH2)2O(O) CAr;
- 2) a second diester of the formula ArC(O) (OCH2CH2)3O(O) CAr;
- and
- 3) at least one additional ester that is a liquid at 25° C.;
- wherein Ar represents a phenyl or methylphenyl radical, the freezing point of said composition is below the freezing points of said first and second diesters and wherein the combined weights of said first and second diesters constitute at least 50 weight percent of said composition.
