ABSTRACT:
A crosslinking system of perfuoroelastomers curable by peroxidic way comprising:as crosslinking agent, a bis-olefin having general formula:wherein:R1, R2, R3, R4, R5, R6, equal to or different from each other, are H or C1-C5alkyls;Z is a C1-C18linear or branched alkylene or cycloalkylene radical, optionally containing oxygen atoms, or a (per)fluoropolyoxyalkylene radical;the bis-olefin amount, expressed in per cent by weight on the total of polymer, being from 0.6% to 1.8%;peroxides for the peroxidic curing, capable to generate radicals by heating, in an amount from 0.2% to 1.3% by weight on the polymer.
