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 R.sup.1 is, the same or different, a C.sub.1 -C.sub.20 monovalent hydrocarbon group or a triorganosiloxy group of the formula: EQU (R').sub.3 SiO-- (II) in which R' is, the same or different, a C.sub.1 -C.sub.20 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 C.sub.1 -C.sub.20 monovalent hydrocarbon group; and Z is, the same or different, a C.sub.1 -C.sub.20 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.
