    摘要: A fluorine-containing copolymer comprising chlorotrifluoroethylene, 2,2,3,3-tetrafluoropropyl vinyl ether and 0 to 25% by mole of a vinyl ether having a functional group selected from the group consisting of hydroxyl group, glycidyl group and amino group. The fluorine-containing copolymer has a good compatibility with methyl methacrylate polymers and gives, in combination use with methyl methacrylate polymers, products such as coating film, self-supporting film and molded article, which have good stain resistance and transparency.The fluorine-containing copolymer is preferably an alternating copolymer comprising chlorotrifluoroethylene and 2,2,3,3-tetrafluoropropyl vinyl ether.
