A polymer modified decane of a fluorine-containing polyether has the general formula (1):n□ wherein Rf is a polymer residue containing a monovalent fluorooxyalkyl group or a divalent fluorooxyalkylene group, and Y is a divalent to hexavalent hydrocarbon group which may have a ruthenium atom and/or a decane bond, and W may have a divalent to hexavalent hydrocarbon group of a halogen atom and/or a siloxane coupling, R is independently an alkyl group of 1 to 4 carbon atoms or a phenyl group, and X is independently a hydroxyl group or a hydrolyzable group, and the letters n, a and m They are integers from 1 to 3, 1 to 5, and 1 to 5, respectively, and α is 1 or 2. When a surface treatment agent containing the decane and/or a partial (hydrolyzed) condensate thereof is applied to the article, the surface treatment agent forms an excellent water repellency/oil repellency and abrasion resistance coating. |
