Beschreibung
Zusammenfassung:	An acrylic copolymer rubber which is a random copolymer of (A) a cyano group-containing acrylate or methacrylate of the following formula (I): wherein R is hydrogen or methyl, and R is -CnH2n- or -CH2CH2-O-CH2CH2-, wherein n is an integer of from 2 to 4, (B) at least one of ethyl acrylate and n-butyl acrylate, and (C) at least one of glycidyl methacrylate and allyl glycidyl ether, or vinyl chloroacetate, wherein the amounts of units derived from the above (A), (B) and (C) in said copolymer are from 5 to 70% by weight, from 20 to 94.5% by weight and from 0.5 to 10% by weight, respectively, and which has a Mooney viscosity ML1+4 (100 DEG C) of at least 5. [Effect] An acrylic copolymer rubber excellent in the fuel oil resistance, cold resistance and heat resistance, is obtainable.
