Disclosed is a fluorine-containing polymer prepared by polymerizing: (I) a polyfluoroalkyl group-containing (meth)acrylate, in the presence of: (II) an isocyanate compound blocked with a pyrazole compound or a malonate ester. A water- and oil-repellent composition containing the fluorine-containing polymer can impart the excellent water- and oil-repellency, and excellent durability thereof to substrates.

Fluoropolymers and surface treatment agent

A stain remover which comprises a copolymer made from as essential ingredients (a) a polymerizable monomer having a polyfluoroalkyl group with less than 8 carbon atoms and represented by the general formula HC&#x2550;CXCOO&#x2014;Y&#x2014;Rf and (b) a fluorine-free polymerizable monomer represented by the following general formula: HC&#x2550;CXCOO&#x2014;(RO)&#x2014;X. The stain remover is effective in minimizing the amount of an organic solvent to be used. It imparts to a substrate the excellent property of removing stains therefrom and a satisfactory texture.
