Japanese Patent JP7276464

B2

A surface treatment agent that comprises a fluoropolyether-group-containing polymer represented by general formula (1), which has a hydroxylated silyl group or a hydrolyzable silyl group, and/or a product of partial (hydrolytic) condensation of the polymer. The surface treatment agent is capable of forming cured coating films which are excellent in terms of water and oil repellency and resistance to wear by steel wool and have a small water-sliding angle.        Formula (1):     Rf-[CH(V)₂]_α(In the formula, Rf is a mono- or divalent residue of a polymer including a fluorooxyalkylene group, the V moieties each independently are a monovalent group having a hydroxylated silyl group or hydrolyzable silyl group at the end and having no polar group besides the hydroxylated silyl group or hydrolyzable silyl group, and α is 1 or 2.)
