<p>Stabilised vinyl fluoride polymers are obtained by mixing a vinyl fluoride polymer contg. at least 75% wt. vinyl fluoride with a stabilising system contg. (I) an aliphatic polyol with 2-8 OH groups per 2-15C atoms, (II) an alkylphenol of formula (II), and (III) a tris(hydrocarbyl)phosphite of formula (III). R1 = H, alkyl or -SR; R = alkyl; R2 = alkyl, or an alkylhydroxyaromatic or thio-hydroxyaromatic gp; R3, R4 and R5 = C1-13 hydrocarbyl.</p> |
