The water- and oil-repellent property can be imparted to the surface of the article, and the water- and oil-repellent composition having excellent durability (washing durability and heavy rain durability) and the water- and oil-repellent property, and further, the reduction of the water- and oil-repellent property due to washing and heavy rain Provide less goods. A method for producing a water / oil repellent composition, wherein a monomer component containing a monomer (a) is polymerized in the presence of a surfactant and a polymerization initiator in the presence of a compound (x). Monomer (a): a compound represented by (ZY) n X. However, Z is a divalent organic group or a single bond, n is 1 or 2, X is a polymerizable unsaturated group, such as a C1-C20 polyfluoroalkyl group. Compound (x): A compound having two or more groups represented by-(CH 2 ) a -CHR 1- (CH 2 ) b -SH. However, R 1 is a methyl group or an ethyl group, a is an integer of 0-2, b is 0 or 1. |
