Antisticking and antiblocking elastomeric compositions comprising copolymers of ethylene, alkyl acrylates, and half esters of 1,4 butenedioic acid and organic acid phosphates

摘要

The antisticking and antiblocking properties of ethylene/methyl or ethyl acrylate/1,4-butenedioic acid monoalkyl ester terpolymers is improved by mixing with said terpolymer a small quantity of a C12-C24 straight chain alkyl or alkenyl acid phosphate or a C12-C24 straight chain alkyl- or alkenyloxypoly(ethyleneoxy) acid phosphate.
