Abstract

Fluoroelastomeric compositions peroxy-curable, endowed with improved characteristics of processability and compatibility, and with enhanced low-temperature properties, comprising, as additives, vinylidene fluoride cotelomers having the general formula: EQU R[(CH.sub.2 CF.sub.2).sub.n (C.sub.3 F.sub.6).sub.m (C.sub.2 F.sub.4).sub.p (C.sub.2 F.sub.3 Cl).sub.q ]X (I) wherein: PA0 X=Br, I; PA0 R is a possible halogenated alkyl radical; PA0 n, m, p, q are integers, m, p, q may also be zero.
