- PROCESS FOR CONTROLLED HYDROLYSIS AND CONDENSATION OF EPOXY-FUNCTIONAL ORGANOSILANES AND THE COCONDENSATION THEREOF WITH FURTHER ORGANOFUNCTIONAL ALKOXYSILANES

摘要

Using The present invention uses the water of an alkoxy functional group 1 from 0.001 to 5 moles per mole of the used silane, acid except as any additional hydrolysis or condensation catalyst is also a hydrolysis catalyst and condensation component of not do, the condensed water formed in the reaction Si-OB and / or Si-O-Si to that of, based on the combined epoxy of the formula I - functional silane and add one or more of formula II optionally in the organofunctional It relates to an adjustment method of silane hydrolysis and condensation. [Formula I] Wherein, R ¹ is or img file="112010009640116-pct00015.jpg" he = "21" id = "i0015" img-format = "jpg" wi = "65" and / group, And R, R 'and R' 'groups are the same or different and are each a hydrogen (H), or 1 to 6 carbon linear, branched or cyclic optionally substituted alkyl group having atoms, A and A 'groups are the same or different and each is a divalent alkyl group having 1 to 10 carbon atoms, R ² and the groups are the same or different and each, R ² is from 1 to 20 carbon linear, branched or cyclic optionally substituted alkyl group, m is 0 or 1. [Formula II] Wherein, R ² is an organofunctional group as already defined above, R 'is methyl, R groups are each independently hydrogen, or one to six carbon atoms having linear, branched, or cyclic alkyl group, n is 0 or 1. ;
