ACRYLIC RUBBER COMPOSITION, CROSSLINKABLE ACRYLIC RUBBER COMPOSITION AND ITS CROSSLINKED PRODUCT

摘要

PROBLEM TO BE SOLVED: To obtain an acrylic rubber composition which, if treated for crosslinking, gets excellence in heat resistance and especially shows a very small change in expansion when loaded with heat, as compared with a conventional acrylic rubber composition; a crosslinkable rubber composition; and a crosslinked product. ;SOLUTION: The acrylic rubber composition can be obtained by mixing (b) an aromatic secondary amine compound and (c) a nickel dialkyldithiocalbamate in (a) an acrylic rubber. A crosslinking agent is added to the acrylic rubber composition to obtain the crosslinkable rubber composition. The crosslinkable rubber composition is treated for crosslinking to obtain the crosslinked product.;COPYRIGHT: (C)2001,JPO
