    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.

    Abstract: A curable composition iaciudes a polyoxyalkylene-based polymer (A); and a (meth)acrylate-based polymer (B), wherein the polyoxyalkylene-based polyer (A) has more than 1.0 reactive silicon group on average per one terminal portion, and the (meth)acrylate-based polymer (B) has more than or equal to 1.0 reactive silicon group on average per one molecule, wherein the (meth)acrylate-based polymer (B) is represented by the formula (1): —SiRX2 (1) wherein R is a hydrocarbon group having 1-20 carbon atoms or a hydrocarbon group having 1-20 carbon atoms substituted with a hetero atom-containing group or a halogen atom, and X is a hydroxyl group or a hydrolyzable group.
