Abstract
A hardenable copolymer containing copolymerization molecular constituents from a fluorinated monomer and an allylic compound, characterized in that: PA1 (a) the fluorinated monomer molecular constituents originate from the combination of tetrafluoroethylene and chlorotrifluoretyhylene, PA1 (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: EQU CH.sub.2 .dbd.CH--O--R PA1 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.
