Claims13
A moisture-curable silylated resin of the general formula (I):
- wherein:
- G is a moiety of general structure (II):
- each R1 is independently an alkyl group of from 1 to 6 carbon atoms;
- each R2 is independently an alkyl group of from 1 to 4 carbon atoms or phenyl group;
- each R3 is independently an alkylene group of from 1 to 12 carbon atoms;
- each R4 is independently an alkyl group of from 1 to 6 carbon atoms, phenyl group, hydrogen or —R3SiR23-a(OR1)a group;
- each R5 is independently a divalent organic group selected from the group consisting of an alkylene group having 1 to 16 carbon atoms, a cycloalkylene group having 5 to 16 carbon atoms and the group X1 having the general formula (III):
- wherein each R6 is independently an alkylene group of from 1 to 12 carbon atoms or a cycloalkylene group of from 5 to 16 carbon atoms;
- each R7 is an alkylene group of from 2 to 12 carbon atoms;
- each R8 is an alkylene group of from 2 to 12 carbon atoms;
- each R9 is independently selected from the group consisting of R7 and R8;
- each R10 is independently a divalent organic group selected from the group consisting of an alkylene group of from 1 to 12 carbon atoms, a cycloalkylene group of from 5 to 16 carbon atoms, X1 and the group X2 having the general formula (IV):
- and,
- subscripts a, b, c, m and n are integers wherein a is 1 to 3;
- b is 0 or 1;
- c is 0 to 5;
- m is 1 to 100;
- and, n is 0 to 100, with the provisos that when b is 0, R4 is hydrogen;
- when n is 0,R7 is a branched alkylene group of from 3 to 12 carbon atoms;
- and, when n is 1 to 100, R7 and R8 are different straight chain alkylene groups in which R7 is at least one straight chain alkylene group possessing an even number of carbon atoms and R8 is at least one straight chain alkylene group possessing an odd number of carbon atoms.
