Curable polymer composition comprising organic polymer having silicon-contaiing reactive group
First Claim
1. A curable polymer composition consisting essentially of(A) 100 parts by weight of an organic polymer having a backbone selected from the group consisting of polymers of polyethers and polymers and copolymers of, vinyl compounds and diene compounds and 1.2 to 6 silicon-containing reactive groups on the average of the formula:
- ##STR13## wherein R1 is, the same or different, a C1 -C20 monovalent hydrocarbon group or a triorganosiloxy group of the formula;
space="preserve" listing-type="equation">(R'"'"').sub.3 SiO-- (II)in which R'"'"' is, the same or different, a C1 -C20 monovalent hydrocarbon group;
X is a hydroxyl group or a hydrolyzable group provided that when the number of Xs in the group (I) is at least 2, Xs are the same or different;
a is 0, 1, 2 or 3;
b is 0, 1 or 2; and
m is an integer of 1 to 18, and(B) 0.01 to 10 parts by weight of a curing catalyst selected from the compounds of the formulas;
##STR14## wherein Q is a C1 -C20 monovalent hydrocarbon group; and
Z is, the same or different, a C1 -C20 monovalent hydrocarbon group or an organic group having a functional residue which can form a coordinate bond with Sn atom.

Abstract
A curable polymer composition comprising
(A) 100 parts by weight of an organic polymer having at least one silicon-containing reactive group of the formula: ##STR1## wherein R1 is, the same or different, a C1 -C20 monovalent hydrocarbon group or a triorganosiloxy group of the formula:
(R'"'"').sub.3 SiO-- (II)
in which R'"'"' is, the same or different, a C1 -C20 monovalent hydrocarbon group; X is a hydroxyl group or a hydrolyzable group provided that when the number of Xs in the group (I) is at least 2, Xs are the same or different; a is 0, 1, 2 or 3; b is 0, 1 or 2; and m is an integer of 1 to 18, and
(B) 0.01 to 10 parts by weight of a curing catalyst selected from the compounds of the formulas: ##STR2## wherein Q is a C1 -C20 monovalent hydrocarbon group; and Z is, the same or different, a C1 -C20 monovalent hydrocarbon group or an organic group having a functional residue which can form a coordinate bond with Sn atom, which can be quickly cured and particularly useful as a pressure sensitive adhesive and a sealing material.
