摘要

The oxetane silane comprises a silane with one or more oxetane groups and organically modified silane obtained by reaction between allyl-functionalized oxetane and hydrosilane. The oxetane is obtained by hydrosilification of an allyl ether functionalized alkoxylated oxetane of a tri- or polyfunctional alcohol with at least one hydrosilane. The oxetane silane comprises a silane with one or more oxetane groups with organically modified silane obtained by reaction between allyl-functionalized oxetane and hydrosilane. It has the general formula of (I). [Image] n : 1-50; R1hydrogen, alkyl, aryl, aralkyl or alkaryl; R2hydrogen, alkyl, aryl, aralkyl, alkaryl or hydroxyalkyl; R3alkylene or arylene; R4alkylene, cycloalkylene or arylalkylene; R6chlorine, alkyl, aryl, alkoxy, alkaryl, or a group of formula (II); [Image] R5hydrogen, alkyl, aryl or a group with a formula of -[OSiR6R6R6]m (III); m : 1-500; The oxetane is obtained by hydrosilification of an allyl ether functionalized alkoxylated oxetane of a tri- or polyfunctional alcohol with at least one hydrosilane.
