Abstract
The invention relates to a novel fluorine-containing copolymer which comprises 25-75 mol % of chlorotrifluoroethylene, 10-70 mol % of a vinyl or isopropenyl ester of fatty acid and 3-40 mol % of allylglycidyl ether and may optionally comprise additional comonomer(s) such as an acrylate. This copolymer possesses favorable properties characteristic of fluororesins, is soluble in various organic solvents and is curable with a compound having a functional group that reacts with epoxy group. A coating liquid using this copolymer gives a hard, stable and transparent coating film on either metal surface or glass surface.
Claims8
A curable copolymer comprising:
- 25 to 75 mol % of first repeating units which originate from chlorotrifluoroethylene;
- 10 to 70 mol % of second repeating units which originate from a fatty acid ester represented by the general formula (1), ##STR3## wherein R is hydrogen atom or methyl group and R' is an alkyl group having 1 to 12 carbon atoms;
- and
- 3to 40 mol % of third repeating units which originate from allylglycidyl ether represented by the formula ##STR4##
