SILICONE MONOMERS AND OLIGOMERS HAVING A CARBOXYL FUNCTIONAL GROUP THEREON

摘要

Provide organic silane compound contain one or more carboxyl acid groups (multiple) can be by following general formula (I), in which: R may be the same or different, and be hydrogen and monovalent hydrocarbon, and instead of alkyl; R1 can be identical or different, can be substituted or unsubstituted alkyl, substituted or unsubstituted aryl, alkenyl, alkynyl or-R2-Bnl-R3 functions; X can be zero to 3; R2 is 1-12 carbon atom of straight chain or branched alkylene; B-NR6, sulphur or oxygen; R6 is hydrogen or low alkyl group (C 1-6); N? 1 is zero or 1; F is linear or 1-10 carbon atom of branched alkylene; N is zero or 1, condition be if it is 1 that n1, which is 1, n, and if n1 be 0, n 0; R3 is (II); Does is R5 hydrogen, low alkyl group (C 1-6?) or alkali metallurgy
