ABSTRACT:
An acrylic copolymer elastomer is disclosed, comprising (A) from 94.5 to 50% by weight of ethyl arcylate or ethyl arcylate containing not more than 50% by weight of n-butyl acrylate, (B) from 5 to 50% by weight of an arcylic acid ester and/or a methacrylic acid ester represented by formula (I): ##STR1## wherein the symbols are as defined in the appended claims, and (C) from 0.5 to 10% by weight of at least one of allyl glycidyl ether and glycidyl methacrylate, or vinyl chloroacetate, and having a Mooney viscosity (ML.sub.1+4, 100.degree. C.) of at least 10. This is a novel copolymer elastomer which is excellent in fuel resistance and low-temperature resistance.
