PROBLEM TO BE SOLVED: To provide fluoropolyether group-containing polymer modified silane capable of forming a cured coated film excellent in water and oil repellency and abrasion resistance, a surface treatment agent containing the silane and/or a partial (hydrolysis) condensate thereof, and an article surface treated with the surface treatment agent.SOLUTION: There is provided fluoropolyether group-containing polymer modified silane represented by the general formula (1), where Rf is a monovalent fluorooxyalkyl group or bivalent fluorooxyalkylene group-containing polymer residue, Y is di- to hexa-valent hydrocarbon group and may have a silicon atom and/or a siloxane bond, W is di- to hexa-valent hydrocarbon group and may have a silicon atom and/or a siloxane bond, R is independently an alkyl group or a phenyl group having 1 to 4 carbon atoms, X is independently a hydroxyl group or a hydrolyzable group, n is an integer of 1 to 3, a is an integer of 1 to 5, m is an integer of 1 to 5 and α is 1 or 2.SELECTED DRAWING: None |
