Abstract

To provide a water/oil repellent composition whereby it is possible to obtain an article which is excellent in each of water repellency, oil repellency and heavy rain durability, a method for its production, and an article which is excellent in each of water repellency, oil repellency, heavy rain durability and texture. The water/oil repellent composition comprises a copolymer containing structural units based on a monomer (a), structural units based on a monomer (b) and structural units based on a monomer (c). Here, the monomer (a) is a compound represented by (Z—Y)X (wherein Z is a Cperfluoroalkyl group, etc.; Y is a bivalent organic group, etc.; n is 1 or 2; and X is a polymerizable unsaturated group). The monomer (b) is a (meth)acrylate having no polyfluoroalkyl group and having an alkyl group with at least 12 carbon atoms. The monomer (c) is a monomer having a poly(oxypolyfluoroalkylene) chain.
