Abstract

Il metodo prevede l'impiego di una composizione polimerica specificata comprendente cloruro di polivinile (A), uno stabilizzante (B), un riempitivo minerale (C) e/o un plastificante (D), in cui A e B vengono immessi senza premescolamento adiacenza ad una prima parte di segmento propulsivo di due rotori di estrusore isomorfi adiacenti compenetrati reciprocamente e a segmenti alterni (longitudinalmente) consecutivi di propulsione e di impasto, almeno uno tra C e D viene introdotto a valle del primo segmento propulsivo e di almeno una parte di segmento di impasto, e la miscela viene degassificata ed estrusa attraverso una matrice d'estrusione.
