Patent ID: 8394870

Claim:
A process for the manufacture of a crosslinked fluoropolymer network, said process comprising: A) providing a telechelic diacrylate copolymer of formula CH 2 ═CR′COO—(CH 2 ) n —R—(CH 2 ) n —OOCCR′═CH 2 , wherein R′ is H or —CH 3 , n is 2 or 3 and R is an oligomer having a number average molecular weight of 1000 to 25,000 daltons, said oligomer selected from the group consisting of i) an oligomer comprising copolymerized units of vinylidene fluoride and perfluoro(methyl vinyl ether), ii) an oligomer comprising copolymerized units of vinylidene fluoride and hexafluoropropylene, iii) an oligomer comprising copolymerized units of tetrafluoroethylene and perfluoro(methyl vinyl ether), and iv) an oligomer comprising copolymerized units of tetrafluoroethylene and a hydrocarbon olefin; B) mixing said diacrylate copolymer with a source of free radicals selected from the group consisting of photoinitiators and organic peroxides to form a curable composition; and C) generating free radicals to form a crosslinked fluoropolymer network.
