To provide a copolymer which is capable of providing an article surface with a dynamic water repellency and which has extremely excellent washing durability of water repellency and oil repellency, while placing little burden on the environment; a method for its production; and a water/oil repellent composition.
A copolymer comprising structural units of the monomer (a) and structural units of the monomer (b), wherein the total of the content of structural units based on the monomer (a) and the content of structural units based on the monomer (b) is at least 85 mass% of all structural units (100 mass%), and the molar ratio ((a)/(b)) of the content of structural units based on the monomer (a) to the content of structural units based on the monomer (b) is from 0.12 to 3; and a water/oil repellent composition containing such a copolymer. Momomer (a): a compound represented by (Z-Y)n-X, wherein Z is a C1-6 polyfluoroalkyl group or the like, Y is a bivalent organic group or a single bond, n is 1 or 2, and when n is 1, and X is a polymerizable unsaturated group. Monomer (b): a halogenated olefin.
