Abstract:
The invention relates to novel linear, semi-crystalline fluoropolymers containing 0.5 to 25 mole percent of at least one vinyl ester monomer unit. At least 40 mole percent of the vinyl ester monomer units are present in the copolymer as single monomer units (not diads or triads or greater) between two fluoromonomer units. The invention also relates to a process for forming the fluoromonomers/vinyl ester copolymer. The fluoropolymer of the invention may be used in applications benefiting from a functional fluoropolymers including as a binder or coating in batteries, or for use in forming hydrophilic membranes and hollow fibers.

Claim (Index 1):
A process for forming a random, semi-crystalline copolymer comprising from 80 to 99.95 mole percent of one or more fluoromonomers, wherein said fluoromonomers comprise from 70 to 100 weight percent of vinylidene fluoride, and 0.05 to 20 mole percent of one or more vinyl ester having the formula CH 2 \u2550CH\u2014O\u2014(CO)\u2014Rn, wherein Rn is a hydrogen atom or a C14 linear or branched hydrocarbon, and wherein at least 40 mole percent of the vinyl ester monomer units are present in the copolymer as single monomer units between two fluoromonomer units, comprising the steps of:\n a) charging an initial monomer charge comprising fluoromonomers, and b) starve-feeding the vinyl ester monomer co-continuously with fluoromonomers to the reactor once polymerization has begun.
