Curable polymer composition

Claim 1

A moisture curable polymer composition comprising (A) an organic polymer having (i) at least one reactive silicon-containing group in a molecule which group is capable of effecting a condensation reaction in the presence of moisture or a cross linking agent and represented by the formula: ##STR38## wherein R is a C 1 -C 20 alkyl or cycloalkyl group, a C 6 -C 20 aryl group, a C 7 -C 20 aralkyl group or a triorganosiloxy group of the formula: (R').sub.3 SiO-- wherein R' is, the same or different, a C 1 -C 20 monovalent hydrocarbon group, X is a hydroxyl group or, the same or different, a hydrolyzable group, a is 0, 2, or 3, b is 0, 1 or 2, and m is an integer of 0 to 18, and (ii) said organic polymer having a backbone selected from the group consisting of a backbone comprising units derived from an acrylate or methacrylate monomer of the formula: ##STR39## wherein R 3 is a hydrogen atom or a methyl group and R 4 is a C 1 -C 20 C 20 alkyl group and a backbone comprising units of the formula: --R.sup.11 --O-- wherein R 11 is a C 1 -C 8 organic divalent group, and (B) a compound selected from the group consisting of a compound having one silanol group in a molecule and a compound which reacts with water to form a compound having one silanol group in a molecule.
