Abstract
A hardenable, fluorinated copolymer of fluorinated monomers and a hydroxylated and/or epoxidized allyl ether, paints and varnishes comprising such copolymers, and the process of making such copolymer.
Claims7
A hardenable copolymer containing the copolymerization radicals of a fluorinated monomer and a hydroxylated and/or epoxidized allyl ether, wherein:
- (a) the fluorinated monomer radicals originate from the association of vinylidene fluoride and at least one fluorinated monomer selected from tetrafluoroethylene, chlorotrifluoroethylene, or hexafluoropropylene, and
- (b) the allyl ether radicals originate from a compound of formula:
- ##STR5## wherein R is CH.sub.2 OH or ##STR6## R.sub.1 is H or CH.sub.3, R.sub.2 is ##STR7## wherein p is a number from 0 to 3,
- X is (CH.sub.2).sub.q --O with q a number from 1 to 3,
- R.sub.5 and R.sub.6, which can be identical or different, each being H,CH.sub.2 OH, CH.sub.2 --CH.sub.2 --OH, or CH.sub.3,
- R.sub.3 and R.sub.4, which can be identical or different, each being H or OH, and
- n and m, which can be identical or different, and each being a number from 0 to 2.
