PURPOSE: To obtain the titled elastomer having excellent heat-resistance without lowering oil resistance, by copolymerizing a specific monomers comprising alkyl acrylate, etc., fluoroalkyl acrylate and vinyl monomer containing epoxy group. n CONSTITUTION: The objective elastomer can be produced by copolymerizing (A) an alkyl acrylate having 1W8C alkyl group (preferably ethyl acrylate or n-butyl acrylate) and/or an alkoxyalkyl acrylate having 2W8C alkoxyalkyl group (preferably 2-methoxyethyl acrylate or 2-ethoxyethyl acrylate), (B) a fluoroalkyl acrylate of formula CH 2 =CRCOOCH 2 (CF 2 ) n R (R is H or methyl; n is 1W8) and (C) at least one compound selected from epoxy group-containing vinyl monomer, carboxyl group-containing vinyl monomer, reactive halogen- containing vinyl monomer and hydroxyl group-containing vinyl monomer. n COPYRIGHT: (C)1988,JPO&Japio |
