Abstract
The present invention pertains to blends of crosslinkable vinylidene fluoride copolymers comprising recurring units derived from hydrophilic monomers, said blend being useful for producing shaped articles characterized by improved performances.
Claims15
A crosslinkable composition (C) comprising:
- A) at least one fluoropolymer [polymer (FA)] comprising:
- (i) recurring units derived from vinylidene fluoride (VDF) monomer;
- (ii) recurring units derived from at least one hydroxyl group-containing vinyl monomer (HA),
- wherein the total amount of recurring units (ii) in said polymer (FA) is of at most 10.0% by moles, with respect to the total moles of recurring units of polymer (FA);
- said polymer (FA) being characterized by a fraction of randomly distributed units (HA) of at least 40%;
- and
- B) at least one a fluoropolymer [polymer (FB)], different from polymer (FA), comprising:
- (i) recurring units derived from vinylidene fluoride (VDF) monomer;
- (iii) recurring units derived from at least one carboxyl group-containing vinyl monomer (CA);
- wherein the total amount of recurring units (iii) in said polymer (FB) is of at most 10.0% by moles, with respect to the total moles of recurring units of polymer (FB);
- said polymer (FB) being characterized by a fraction of randomly distributed units (CA) of at least 40%;
- and
- further comprising at least one acidic crosslinking catalyst.
