The invention pertains to a thermoplastic vulcanizate fluorine-containing composition [vulcanizate (C)], comprising a continuous thermoplastic fluoropolymer phase and a dispersed vulcanized fluoroelastomer phase, said composition comprising: -at least one thermoplastic, fluoropolymer [polymer (F)], said polymer (F) comprising (j) from 40 to 60% by moles of recurring units derived from ethylene (E); (jj) from 60 to 40% by moles of recurring units derived from at least one of chlorotrilluoroethylene (CTFE) and tetrafluoroethylene (TFE); and (jjj) from 0.5 to 10% by moles of recurring units derived from of at least one (per)fluoroalkylvinylether of formula CX2CXOR.sub.f, wherein each of X, equal to or different from each other, is independently H or F (preferably F); and R.sub.f is a C.sub.1-C.sub.12 (per)fluoroalkyl group or a C.sub.1-C.sub.12 (per)fluoro-oxy-alkyl group comprising one or more than one catenary oxygen atoms [monomer (V)], with % by moles being referred to the total moles of recurring units of the polymer (F); and -at least one (per)fluoroelastomer [elastomer (A)].

Copolymers of one or more halogenated olefins and one or more halogenated co-monomers selected from the group consisting of halogenated alkenyl ethers, halogenated alkenyl esters, and halogenated (meth)acrylates are useful in various end-use applications wherein the presence of halogen (e.g., fluorine) in the copolymer imparts one or more desirable properties, as compared to analogous copolymers not containing halogen.

Disclosed are a method for a preparing fluorine- and chlorine-containing conductive polymer resin, a single-side or double-side filled composite film prepared using the fluorine- and chlorine-containing conductive polymer resin, and a method for preparing the film. The fluorine- and chlorine-containing conductive polymer single-side or double-side filled composite film comprises a microporous film skeleton and the fluorine- and a chlorine-containing conductive polymer resin. The composite film is mechanically stronger, more waterproof, more impervious to water and toxic and harmful chemicals, and more moisture permeability. When applied to biochemical protective clothing, it can greatly enhance the combat effectiveness of the soldiers because it is light and more impervious to water and toxic and harmful chemicals, brings about comfort, and keeps the soldiers warm. When applied to fuel cells, it can provide better electrical properties due to its high conductivity and can allow the fuel, such as hydrogen or alcohol, to burn more completely.

The present invention relates to a method for manufacturing of partially fluorinated polymers, notably vinylidene fluoride (VDF)-based polymers, in emulsion polymerization, and to a polymer obtained from said method.
