The extrusion of a vinylidene chloride interpolymer pellets is improved by coating with at least one processing aid. Exemplary, processing aids are fatty acids, esters, fatty alcohols, fatty amides, metallic salts of fatty acids, olefin polymers and polyolefin waxes. On a amélioré l'extrusion de pellets d'interpolymère de chlorure de vinylidène par revêtement avec au moins un auxiliaire de traitement. On peut citer à titre d'exemple d'auxiliaire de traitement des acides gras, esters, alcools gras, amides gras, sels métalliques d'acides gras, polymères d'oléfines et cires de polyoléfines.
