Zusammenfassung:	To provide a fluorinated copolymer which presents little burden on the environment and is capable of imparting excellent water repellency to a surface of an article, a process for its production, a water repellent composition using such a fluorinated copolymer, and an article having a surface treated with such a water repellent composition. A fluorinated copolymer comprising, in specific ratios, units derived from F(CF 2 ) 6 CH 2 CH 2 OC(O)C(CH 3 )=CH 2 , units derived from vinyl chloride, units derived from vinylidene chloride, units derived from an alkyl (meh)acrylate having a C 12-30 alkyl group, and units derived from a monomer having no fluoroalkyl group and having a cross-linkable functional group, wherein units derived from F(CF 2 ) n CH 2 CH 2 OC(O)C(CH 3 )=CH 2 (wherein n is an integer of from 1 to 5) are in at most a specific ratio; a water repellent composition containing such a fluorinated copolymer; and an article treated with such a water repellent composition.
