FLUOROOXYALKYLENE GROUP-CONTAINING POLYMER MODIFIED SILANE AND SURFACE TREATMENT AGENT COMPRISING SAID SILANE AND ARTICLE TREATED WITH SAID SURFACE TREATMENT AGENT

摘要

The present invention provides a fluorooxyalkylene group-containing polymer-modified silane capable of forming a water / oil repellent layer having excellent heat resistance, a surface treating agent comprising the silane and / or a partial hydrolysis condensate thereof, and an article treated with the surface treating agent. do. Fluorooxyalkylene group containing polymer modified silane represented by following General formula (1). Wherein Rf is a monovalent or divalent straight chain fluorooxyalkylene group containing polymer moiety, b is 0 to 10 on average, Z is a 2 to 6 valent group which may independently have a siloxane bond, and R is Is independently an alkyl or phenyl group having 1 to 4 carbon atoms, X is independently a hydrolyzable group, a is independently 2 or 3, y is an integer of 1 to 5 independently, and α is an integer of 1 to 5 , β is 1 or 2)
