ACRYLIC RUBBER, CROSSLINKABLE ACRYLIC RUBBER COMPOSITION AND MOLDINGS

摘要

An acrylic rubber consisting of a copolymer comprising 0.1 to 20 wt% of monomer units (A) derived from a butenedioic acid monoester having an alicyclic structure and 50 to 99.9 wt% of monomer units (B) derived from at least one monomer selected from among acrylic esters and methacrylic esters. A crosslinkable acrylic rubber composition comprising the acrylic rubber and a crosslinking agent (particularly a polyamine-type crosslinking agent) is excellent in processing stability and moldability and can give moldings excellent in heat resistance and compression set characteristics.
