Abstract:
A polymer (A) having, at one terminal moiety thereof, a terminal structure having two or more carbon-carbon unsaturated bonds. A reactive-silicon-group-containing polymer (B) having, at one terminal moiety thereof, a terminal structure having two or more reactive silicon groups.
Abstract:
Provided are reactive silicon group-containing polymers and a curable composition containing said polymers. The curable composition provides a cured product having a low modulus, flexibility, excellent tensile strength, tensile elongation, and tear strength. The curable composition can also exhibit excellent rapid curing properties even when a low-activity catalyst has been added. In the reactive silicon group-containing polymer, a reactive silicon group, indicated by general formula (1): (—Si(R1)3-a(X)a), is bonded to the molecular chain of the polymer and an atom adjacent to the reactive silicon group has an unsaturated bond. In general formula (1), each R1 can independently indicate a C1-20 hydrocarbon group, and the R1 hydrocarbon groups can be substituted and a hetero-containing group can be used. X can be a hydroxyl group or a hydrolyzable group, and a is 1, 2, or 3.

Abstract:
A curable composition contains a hydrolyzable silyl group-containing polyoxyalkylene polymer (A), silica (B), a silane compound (C) containing an alkyl group having four or more carbon atoms, and a compound (D) resulting from partial condensation of silyl groups of an aminosilane alone or partial condensation of the aminosilane with an alkoxysilane compound other than aminosilanes.
