ABSTRACT:
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 Ar1and Ar2represent 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.
