    Abstract: A multi-part curable composition includes an A part including a polyoxyalkylene polymer (A) having a reactive silicon group, a (meth)acrylic ester polymer (B) having a reactive silicon group, an epoxy resin curing agent (D) having a tertiary amine moiety, an alicyclic structure-containing amine (E1), and a B part including an epoxy resin (C). Each of the reactive silicon groups of the polymer (A) and polymer (B) are represented by —SiR5cX3-c. R5 is a substituted or unsubstituted hydrocarbon group having 1 to 20 carbon atoms, X is a hydroxy group or a hydrolyzable group, and c is 0 or 1. A multi-part curable composition includes an A part including the polymer (A), polymer (B), and an epoxy resin curing agent (D) having a tertiary amine moiety, and a B part including an epoxy resin (C), where either or both of the A and B parts include an amino alcohol compound (E2).

    Abstract: A (meth)acrylic ester copolymer (A) has a reactive silicon group represented by the following formula (1): —SiR1cX3-c (1), wherein R1 is a substituted or unsubstituted hydrocarbon group having 1 to 20 carbon atoms, X is a hydroxy group or a hydrolyzable group, and c is 0 or 1. A monomer component of the (meth)acrylic ester copolymer (A) includes a (meth)acrylic ester (a1), a polyoxyalkylene polymer (a2) having more than one (meth)acryloyl groups per molecule, and a chain transfer agent (a3) having a mercapto group. The molar ratio of the polyoxyalkylene polymer (a2) to the chain transfer agent (a3) is 0.06 or more. The monomer component further includes a monomer (a4) having a reactive silicon group and a polymerizable unsaturated group, and/or the chain transfer agent (a3) further has a reactive silicon group.

    Abstract: A curable composition includes a (meth)acrylic acid ester polymer (A), wherein the (meth)acrylic acid ester polymer (A) includes a monomer and a macromonomer (a). The monomer includes a reactive silicon group represented by the general formula (1): —SiR1aX3-a (1) (in the formula, R1 represents a substituted or unsubstituted hydrocarbon group with 1 to 20 carbon atoms, X each independently represents a hydroxyl group or a hydrolyzable group, and a represents 0 or 1.) and a polymerizable unsaturated group. The macromonomer (a) is a (meth)acrylic acid ester polymer having a polymerizable unsaturated group.

    Abstract: The present invention aims to provide a curable composition that is usable in fast curing adhesives and the like and has excellent curability and excellent initial adhesion. The aim is accomplished by use of a curable composition that contains a polyoxyalkylene polymer (a1) having a reactive silyl group (e.g., trimethoxysilyl group) equivalent of 0.15 mmol/g to 1.5 mmol/g and a polyoxyalkylene polymer (a2) having a reactive silyl group equivalent of 0.010 to 0.14 mmol/g. Preferably, the polymers (a1) and (a2) both have a backbone with at least one branch.
