Abstract
A cross-linkable copolymer formed by polymerizing in solution vinylidene fluoride, tetrafluoroethylene, an allyl ether, and a vinyl ether and protective coating prepared utilizing such copolymer.
Claims7
A cross-linkable copolymer containing the copolymerization radicals of a fluorinated monomer, a hydroxylated allyl ether and a vinyl ether, wherein:
- (a) the fluorinated monomer radicals originate from the association of vinylidene fluoride and tetrafluoroethylene,
- (b) the allyl ether radicals originate from a compound of the formula:
- ##STR4## wherein R is CH.sub.2 OH;
- R.sub.1 being:
- H or CH.sub.3 ;
- R.sub.2 is ##STR5## with "p" being a number selected from 0 to 3, X being (CH.sub.2)q--O with "q" a number selected from 1 to 3, and R.sub.5 and R.sub.6, (which can be identical or different) being:
- CH.sub.2 OH, CH.sub.2 --CH.sub.2 --OH, CH.sub.3, C.sub.2 H.sub.5 ;
- R.sub.3 and R.sub.4 being H or OH, but not simultaneously H;
- and "n" and "m", (which can be identical or different) being numbers selected from 0 to 2;
- and
- (c) the vinyl ether radical originate from a compound of the formula:
- CH.sub.2 .dbd.CH--O--R.sub.7, wherein R.sub.7 is a linear or branched alkyl radical containing 2 to 8 carbon atoms or a cyclic radical.
