    摘要: An acrylic elastomer capable of giving a vulcanization product having a distinguished tensile strength and a good stretching even by cross-linking with an organic peroxide can be obtained by using an organic peroxide having a non-conjugated double bond as a polymerization initiator in polymerization of at least one of (a) alkyl acrylates having an alkyl group of 1 to 8 carbon atoms and (b) alkoxyalkyl acrylates having an alkoxylalkyl group of 2 to 8 carbon atoms.

    摘要: A fluorine-containing elastomer comprising vinylidene fluoride, tetrafluoroethylene and hexafluoropropylene having a high fluorine content (e.g. at least 68% by weight) can be vulcanized with a polyol-based cross-linking agent by further copolymerizing 2H-pentafluoropropylene into the elastomer, whereby the resulting vulcanization products having improved characteristics such as rheological properties, normal state physical properties and compression set can be obtained. Vulcanization products obtained by vulcanization with a polyol-based cross-linking agent and a quaternary onium salt compound have a good permeation resistance to fuel oil as a result of a permeation test with a mixed solvent of gasoline/methanol in a volume ratio of 85/15.
