An object of the present invention is to provide a fluoropolyether group-containing polymer denatured decane capable of forming a water-repellent oil-repellent layer excellent in weather resistance, a surface treatment agent containing the decane and/or a partially hydrolyzed condensate thereof, and a surface treatment agent An item that has been surface treated.nThe solution of the present invention is a polymer modified decane containing a fluoropolyether group, which is represented by the following general formula (1);n□n(wherein Rf is a monovalent fluorooxyalkyl group or a divalent fluorooxyalkylene group-containing polymer residue, and Y is a 2 to 6-valent hydrocarbon group which may have a decane bond and a fluorenylene group, R It is independently an alkyl group having 1 to 4 carbon atoms or a phenyl group, X is independently a hydrolyzable group, n is an integer of 1 to 3, m is an integer of 1 to 5, and α is 1 or 2). |
