Hardenable fluorinated copolymer, the process for making the same, and its application in paints and varnishes

Abstract

A hardenable copolymer containing copolymerization molecular constituents from a fluorinated monomer and an allylic compound, characterized in that: (a) the fluorinated monomer molecular constituents originate from the combination of tetrafluoroethylene and chlorotrifluoretyhylene, (b) the molecular constituents from the allylic compound originate from an allylic polyol of formula: ##STR1## in which R.sub.1 is H or CH.sub.2 OH, R.sub.2 is OH or CH.sub.2 OH, R.sub.3 is CH.sub.3 or OH, with the condition that R.sub.1 and R.sub.3 cannot be simultaneously H and CH.sub.3, and that it also contains (c) copolymerization molecular constituents from a vinylic ether of formula: CH.sub.2 .dbd.CH--O--R in which R is a linear or branched chain alkyl radical with 2 to 13 carbon atoms, and the process of making such copolymers and paints and varnishes containing the same.
