Abstract
A hardenable copolymer containing copolymerization molecular constituents from a fluorinated monomer and from an allylic monomer, characterized in that: PA1 (a) the fluorinated monomer molecular constituents originate from the combination of tetrafluoroethylene and at least one other fluorinated monomer selected from chlorotrifluorethylene, vinylidene fluoride, or a mixture thereof, PA1 (b) the allylic monomer is an allylic polyol of formula: ##STR1## in which R.sub.1 is H or CH.sub.2 OH, PA2 R.sub.2 is OH or CH.sub.2 OH, and PA2 R.sub.3 is CH.sub.3 or OH, PA1 with the proviso that R.sub.1 and R.sub.3 cannot be simultaneously H and CH.sub.3, and that it contains: PA1 (c) molecular constituents from an allylic or acrylic monomer with a fluorocarbon chain of formula: ##STR2## in which n has a value of 3 to 12, PA2 R.sub.4 is H or CH.sub.3, and ##STR3## and the process of making such copolymer and paints and varnishes containing the same.
