ABSTRACT:
Multilayers comprising at least one laminate formed in sequence by the following layers:A) one thermoprocessable fluoropolymer layer comprising units deriving from vinylidenfluoride (VDF);B) one polyamide layer blended with 0.01%–5% by weight of a diamine or one polyamide layer having at least 20 μeq/g of —NH2groups, or one thermoprocessable polymer layer containing (—COO—) units and/or —CN groups; andC) one layer based on chlorinated polyvinylchloride (CPVC) containing from 58% to 75% by weight of chlorine.
