ABSTRACT OF THE DISCLOSURE: Cotelomers of vinylidene fluoride with one or more fluoro-olefins, having the general formula: R[(CF2CH2)n (C3F6)m (C2F4)p (C2F3Cl)q] X (I) wherein: X is either Br or I, R is an alkyl radical eventually containing halogen atoms, n is an integer comprised within the range of from 1 to 30, m is an integer comprised within the range of from 0 to 10, p and q are integers comprised within the range of from 0 to 20, and wherein m+p+q is at least 1, obtained by cotelomerizing monomers in the presence of a telogen RX (wherein R and X have the abovesaid meaning) and of a free-radical polymerization initiator. These cotelomers are useful as plasticizing additive in fluoroclastomeric compositions which are peroxycurable.
