Fluoropolymers having diacrylate ends

A process for the manufacture of a telechelic diacrylate copolymer, said process comprising:

• A) providing a diol of formula HO—(CH2)n—R—(CH2)n—OH, wherein 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;
• and
• B) reacting said diol with CH2═CR′COX, wherein X is a halide and R′ is H or —CH3, to form a diacrylate copolymer of formula CH2═CR′COO—(CH2)n—R—(CH2)n—OOCCR′═CH2.
