THERMOPROCESSABLE PER(HALO)FLUOROPOLYMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2012/084749
Kind Code:
A1
Abstract:
The invention pertains to a thermoprocessable composition comprising: - at least one thermoprocessable per(halo)fluoropolymer [polymer (A)]; - at least one inorganic filler [filler (I)]; and - at least one perfluoropolyether block copolymer [polymer (E)] comprising: A) one or more (per)fluoropolyoxyalkylene segment (chain Rf), that is to say a segment comprising recurring units having at least one catenary ether bond and at least one fluorocarbon moiety, and B) one or more polyalkylene segment (chain Ra) comprising recurring units of formula: -(CR1R2-CR3R4)- wherein R1, R2, R3, R4, equal to or different from each other, are selected from the group consisting of H, halogens (preferably F, CI); C1-C6 (hydro)carbon groups, optionally containing fluorine or other heteroatoms, preferably perfluoroalkyi or (per)fluorooxyalkyl.
