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: wherein each of R1, R2, R3, equal or different from each other, is independently an hydrogen atom or a C-Chydrocarbon group, and Ris a hydrogen or a C-Chydrocarbon 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.
