Abstract
To provide a fluorinated copolymer comprising, in specific ratios, units derived from F(CF2)6CH2CH2OC(O)C(CH3)═CH2, units derived from vinyl chloride, units derived from vinylidene chloride, units derived from an alkyl (meth)acrylate having a C12-30 alkyl group, and units derived from a monomer having no fluoroalkyl group and having a cross-linkable functional group, wherein units derived from F(CF2)nCH2CH2OC(O)C(CH3)═CH2 (wherein n is an integer of from 1 to 5) are in at most a specific ratio; a process for producing such a fluorinated copolymer; a water repellent composition containing such a fluorinated copolymer; and an article treated with such a water repellent composition.
