Abstract
This invention relates to oligomers of perfluoro(methyl vinyl ether) with a monomer selected from the group consisting of vinylidene fluoride and tetrafluoroethylene, more particularly said oligomers contain 40-90 mole percent copolymerized units of vinylidene fluoride or tetrafluoroethylene and 10-60 mole percent copolymerized units of perfluoro(methyl vinyl ether), said oligomers having two functional endgroups and having a number average molecular weight between 1000 and 25,000 g/mole.
