Abstract
Abstract A curable polymer composition comprising: (A) 100 parts by weight of an oxyalkylene base polymer having at least one silicon-containing group to the silicon atom of which a hydroxy group and/or a hydrolyzable group is bonded and which is cross linkable through formation of a siloxane bond, (B) 0.1 to 20 parts by weight of at least one compound selected from the group consisting of a compound having one silanol group in a molecule and a compound which, when reacted with moisture, generates a compound having one silanol group in a molecule, (C) 0.1 to 20 parts by weight of a compound having a silicon-containing group to the silicon atom of which two hydrolyzable groups are bonded and an amino group, and (D) 0.01 to 5 parts by weight of a compound having a silicon-containing group to the silicon atom of which three hydrolyzable groups are bonded and an amino group, which composition provides a cured material having low modulus, good bond strength and improved weather resistance of bond strength.
