Abstract
The invention pertains to a thermoplastic VDF polymer composition comprising: at least one thermoplastic vinylidene fluoride (VDF) polymer comprising at least 85% by moles of recurring units derived from VDF; and at least one ethylene/chlorotrifluoroethylene (ECTFE) polymer, wherein said ECTFE polymer possesses a melting point of less than 210° C. and it is comprised in an amount of from 0.1 to 20% wt with respect to the total weight of VDF polymer and ECTFE polymer. The invention also pertains to a process for making the VDF polymer and to the uses thereof for manufacturing films, in particular transparent films.
