Curable compositions based on fluoroelastomers vulcanizable with peroxides.

摘要

Fluoroelastomeric peroxy curable compositions, endowed with improved characteristics of processability and compatibility, and with enhanced low-temperature properties, comprising, as additives, vinylidene fluoride cotelomers having the general formula: (I) R[(CH2CF2)n(C3F6)m(C2F4)p(C2F3Cl)q]X wherein X = Br or I; R is an optionally halogenated alkyl radical; n, m, p, q are integers; m, p, q may also be zero.
