Extrusion processability of non-fluorinated melt-processable polymers is improved by introducing a fluoropolymer process aid by means whereby the weight average particle size of the fluoropolymer is greater than 2 microns as it reaches the extruder die entrance.
Selon la présente invention, la possibilité de traitement par extrusion de polymères non fluorés pouvant être traités à l'état fondu est améliorée par l'introduction d'un adjuvant de traitement fluoropolymère, lequel fluoropolymère présente une granulométrie moyenne en poids supérieure à deux microns lorsqu'il atteint l'entrée de la filière d'extrusion.
