摘要： A fluoroelastomer composition comprising (a) a fluoroelastomer comprising vinylidene fluoride units and units of at least one other fluorine-containing monomer copolymerizable with vinylidene fluoride, said monomer containing 2-7 carbon atoms and containing at least as many fluorine atoms as carbon atoms, and (b) a phosphonate accelerator for curing the fluoroelastomer having the formula:
where R, R₁ and R₂ independently represent an alkyl radical of from 1-8 carbon atoms, a phenyl radical, a phenyl radical substituted with an alkyl group of 1-4 carbon atoms or an aralkyl radical having from 7-13 carbon atoms such fluoroelastomer composition substantially may reduces mold fouling during curing.

摘要： In the cross-linking of polymers containing ethylenic unsaturation, especially natural and synthetic rubbers of the isoprene or styrene-butadiene series, S-acyl derivatives of N-substituted thiohydroxylamines, previously known to be useful as accelerators for vulcanisation by sulphur or sulphur donors, can be used themselves as sole vulcanisation agents. The preferred compounds for this purpose are the N-dithiocarbamoyl derivatives of amines, amides or imides, e.g. S-(N',N'-dimethylamino)-N,N-dimethyldithiocarbamate, S-(acetylamino) N,N-diethyldithiocarbamate or S-(phthalimido)-di-n-butyldithiocarbamate. Typical advantages of the resultant rubbers are better resistance to heat ageing and resistance to compression set when compared with sulphur cured rubbers and greater processing safety than TMTD-cured rubbers.
