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.
