Crosslinkable rubber composition

Abstract

Abstract PURPOSE:To provide the titled composition containing a vinylidene fluoride resin and a specific acrylic rubber as essential components and having excellent heat-resistance, gasoline resistance, sour gasoline resistance, etc., as well as compression set. CONSTITUTION:The objective composition can be produced by compounding (A) a vinylidene fluoride resin containing >=90mol% vinylidene fluoride and having a polymerization degree of 100-100,000 with (B) an acrylic rubber containing epoxy group and carboxyl group, (C) other blendable polymer (e.g. chloroprene rubber, phenolic resin, etc.) at a weight ratio A/(B+C) of 5/95-60/40, preferably 10-90-50/50 and a weight ratio B/C of 100/0-50/50, preferably 100/0-70/30 and compounding 100pts.(wt.) of the obtained composition with (D) 0.1-10pts. of a quaternary ammonium salt and/or quaternary phosphonium salt as a crosslinking agent.
