Abstract
A copolymer comprising: PA1 (a) from 10 to 70% by moles of ethylene, PA1 (b) from 30 to 90% by moles of a fluorinated monomer selected from tetrafluoroethylene, chlorotrifluoroethylene, or their mixtures, PA1 (c) from 0.1 to 30% by moles, with respect to the total amount of monomers (a) and (b), of a hydrogenated monomer having the formula: EQU CH.sub.2 =CH--(CH.sub.2).sub.n --R.sub.1 (I) PA1 where R.sub.1 =--OR.sub.2, --(O).sub.t CO(O).sub.p R.sub.2 with t and p as integers: t=0 or 1 and p=0 or 1 and R.sub.2 is a hydrogenated radical from 1 to 20 carbon atoms C.sub.1 -C.sub.20, branched and/or linear alkyl and cyclo-alkyl radical or R.sub.2 is H. The R.sub.2 radical may optionally contain: heteroatoms preferably Cl, O, N; one or more functional groups, preferably chosen among OH, COOH, epoxide, ester and ether; and double bonds. The n subscript is an integer number between 0 and 10.
