<p>PROBLEM TO BE SOLVED: To provide an acrylic rubber excellent in easy-to-handle property and mechanical strength or the like.SOLUTION: The acrylic rubber has a core-shell structure comprised of a core layer containing no gel content and a shell layer containing a gel content. The core layer contains (a-1) a constitutional unit derived from at least one kind selected from an acrylic acid alkyl ester monomer or an acrylic acid alkoxy alkyl ester monomer and (a-2) a constitutional unit derived from a crosslinkable monomer having at least one kind selected from a group consisting of an epoxy group, a halogen group, a carboxyl group which are crosslinkable groups in a side chain, but no polyfunctional monomer. The shell layer contains (a-3) same constitutional unit as (a-1) and (a-4) a constitutional unit derived from a polyfunctional monomer having a carbon-carbon double bond in its side chain, but no crosslinkable monomer. The core layer contains (a-2) of 0.1 to 3.0 pts.mass based on 100 pts.mass of (a-1). The shell layer contains (a-4) of 0.1 to 3.0 pts.mass based on 100 pts.mass of (a-3).</p> |
