    摘要： Disclosed is a vulcanizable, fluorine-containing elastomer composition comprising (a) a vulcanizable, fluorine-containing elastomer, (b) a polyol vulcanizing agent comprising a polyol compound as a crosslinking agent, and (c) an aliphatic amine compound represented by the formula: R.sub..alpha. NH.sub..beta. wherein R represents an alkyl group, .alpha. represents an integer of from 1 to 3, and .beta. represents 3 minus .alpha.. The vulcanizable, fluorine-containing elastomer composition of the present invention is capable of providing a vulcanization product having not only excellent tensile properties, resistance to heat and oils, and sealability at high temperatures which are comparable to those of vulcanization products of conventional fluorine-containing elastomer compositions, but also having a remarkably improved compression set resistance which has not conventionally been achieved, and the elastomer composition per se is remarkably improved with respect to mold release properties, flowability, roll processability, and workability in vulcanization molding, particularly in vulcanization molding by injection.
