Abstract

The present invention pertains to a linear semi-crystalline copolymer [polymer (A)] comprising recurring units derived from vinylidene fluoride (VDF) monomer and at least one hydrophilic (meth)acrylic monomer (MA) of formula (I) wherein each of R1, R2, R3, equal or different from each other, is independently an hydrogen atom or a C₁-C₃ hydrocarbon group, and R OH is a hydrogen or a C₁-C₅ hydrocarbon moiety comprising at least one hydroxyl group, said polymer (A) comprising from 0.05 to 10 % by moles of recurring units derived from said hydrophilic (meth)acrylic monomer (MA) and being characterized by a fraction of randomly distributed units (MA) of at least 40 %, having improved thermal stability, to a process for its manufacture, to a composition comprising the same, and to its use as binder in batteries or for the manufacture of hydrophilic membranes.
