    摘要: A fluoroelastomer composition which has beneficial utility in the rapid manufacture of cured fluoroelastomer articles having good strength and resistance to compression set can be prepared by blending the following components: (A) an elastomeric copolymer of vinylidene fluoride and another fluorine-containing monomer, and (B) as a vulcanization agent, a carboxylic acid ester of 4,4'-sulfonylidiphenol (for example, 4,4'-sulfonyldiphenol diacetate); and when making the cured articles, it is also preferred to add (C) a suitable metal compound such as a divalent metal oxide or hydroxide, and (D) a suitable accelerator, for example a certain type of quaternary phosphonium compound.
