Abstract

Vulcanisable compsn. based on elastomeric copolymers (I) of vinylidene fluoride with fluorinated or chloro fluorinated olefins or with fluorinated vinyl ethers comprises, as processing additive, 5-15 pts.wt. per 100 pts.wt. (I) of a fluorinated polyamide with recurring units of formula (II)\ \ -COCF2O(CF2O)n-(CF2CF2O)m-CF2CONRANR-\ \ (where the CF2O and CF2CF2O units are distributed statistically along the chain and where n and m are 2-100; m + n is 5-200, ratio m/n is 0.2-1.5; A is (cyclo)alkenyl, arylene, alkylarylene or heterocyclic gp.; R is H, alkyl or phenyl). (II) have inherent viscosity of 0.1-0.6 (0.3% soln. in a 1,1,2-trichloro- trifluoro ethane and DMF mixt. at 20 deg.C).
