VINYLIDENE FLUORIDE COPOLYMERS

摘要

The present invention pertains to a fluoropolymer [polymer (F)] comprising: - recurring units derived from vinylidene fluoride (VDF), and - from 0.01 % to 5% by moles of recurring units derived from at least one (meth)acrylic monomer [monomer (MA)] having formula (I), wherein: - R1, R2 and R3, equal to or different from each other, are independently selected from a hydrogen atom and a C1-C3 hydrocarbon group, and - ROH represents a hydrogen atom or a C1-C5 hydrocarbon moiety comprising at least one hydroxyl group, said polymer (F) comprising end groups having formula -CF2H and/or -CF2CH3 in an amount of at least 30 mmoles per Kg of vinylidene fluoride (VDF) recurring units. The invention also pertains to a process for the manufacture of said polymer (F) and to use of said polymer (F) as binders for the manufacture of electrodes or for the manufacture of membranes.
