ABSTRACT:
A fluorine-containing copolymer for paints, having Mn of 5000 to 50000 and Mw/Mn of 2 to 10, which consists essentially of 30 to 70% by mole of the fluoroolefin unit, 15 to 45% by mole of the vinyl ether or vinyl ester unit, 1 to 30% by mole of the hydroxyalkyl vinyl ether unit, and 4 to 30% by mole of the carboxyl-containing unit wherein the carboxyl group is neutralized in an amount of 30% or more with ammonia or a tertiary amine. This copolymer can give a god coating film without water spots and dewetting as well as with a good levelling property, while maintaining the excellent properties which a fluorine resin has be nature.
