Abstract
An acrylic elastomer obtained by copolymerization of about 60 to about 99.9% by weight of at least one of alkyl acrylate and alkoxyalkyl acrylate; about 10 to about 0.1% by weight of a halogen-containing vinyl compound having a secondary or tertiary halogenoalkyl group; and about 30 to 0% by weight of a monomer copolymerizable with the acrylate and the vinyl compound, sum total being 100% by weight, is an acrylic elastomer containing the halogen-containing vinyl compound as a cross-linking site monomer capable of forming an active halogen group cross-linkable with an organic peroxide or the like, and has a high vulcanization torque.
