<p>A vulcanizable elastomer composition is prepared by blending 100 parts by weight of a copolymer containing (A) 50-85% by mole of ethylene units, (B) 10-45% by mole of an alkyl acrylate unit having the formula (I), <CHEM> wherein R1 is an alkyl having 1-8 carbon atoms, (C) 2-35% by mole of an alkoxyalkyl acrylate unit having the formula (II), <CHEM> wherein R2 is hydrogen or methyl, R3 is an alkylene having 1-4 carbon atoms, and R<4> is an alkyl or alkoxyalkyl, each having 1-4 carbon atoms, and (D) up to 5% by mole of a glycidyl ester unit having the formula (III), <CHEM> wherein R<5> is hydrogen or methyl, and 0.1-10 parts by weight of at least one vulcanizing agent. The vulcanizable composition can give vulcanizates of well-balanced properties having an improved low-temperature resistance and retaining excellent oil resistance.</p> |
