FIELD: chemistry. ^ SUBSTANCE: invention relates to a processing additive for extrusion of polyolefins or thermoplastic resins. The composition contains at least one fluoropolymer (A), at least one inter-phase agent (B) and at least one stabiliser (C). The invention also relates to an extrusion method, which involves: (i) bringing the composition in solid state, as described above in any of claims 1-13, into contact with polyolefin or thermoplastic resin and (ii) extrusion of the mixture obtained at step (i) to obtain a film, pipe, relief or hollow body. ^ EFFECT: additive reduces or eliminates extrusion defects without reducing the yellowing index of the resin subjected to extrusion. ^ 14 cl, 1 dwg, 1 tbl, 6 ex |
