    摘要: The invention concerns to a composition comprising: at least one fluorinated polymer (A), at least one interfacing agent (B), and at least one stabilizer (C) of formula (I) wherein Ar1 and Ar2 represent an aryl group. The composition is used as an agent for extruding a thermoplastic polyolefin or resin. The invention also concerns an extruding method consisting in: (i) contacting in the solid phase a composition as defined above with a thermoplastic polyolefin or a thermoplastic resin; (ii) then extruding the mixture obtained in (i) in the form of a film, a tube, a profiled section or a hollow body.

    摘要: The present invention relates to a composition coextrudable with PVDF and comprising: 30 to 50 parts of PVDF; 70 to 50 parts of a copolymer comprising, by weight, 90 to 50% of methyl methacrylate (MMA) per 10 to 50% of an alkyl (meth)acrylate respectively, the alkyl having from 2 to 24 carbon atoms; 1 to 4 parts of a UV absorber; the total making 100 parts. The invention also relates to coextruded films consisting of this composition as the adhesive layer and a PVDF-based layer of 50 to 100 parts of PVDF per 50 to 0 parts of PMMA respectively. These films possess mechanical properties sufficient to allow them to be used as a coating transparent to visible light but opaque to UV radiation.
