Claim 0:
1. A resin composition comprising:
(i) an organic resin containing at least one carboxylic acid ester or ether functional group; and
(ii) a moisture-curable silylated polycarbonate resin of the general formula (I):, wherein:
G is a moiety of general structure (II):, in which
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):, 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 R7 or 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 1 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 alkylene groups,
wherein the moisture-curable silylated polycarbonate resin (ii) is soluble
within the organic resin (i).
