US Patent 7781559 Curable composition and method for producing the same

Disclosed herein is a curable composition excellent in workability, adhesion properties, rubber-like properties, storage stability, and quick curability. The curable composition comprises (A) a crosslinkable silyl group-containing organic polymer and (B) a (meth)acrylic polymer obtained by polymerizing a (meth)acrylic monomer having a polymerizable unsaturated bond in the presence of a metallocene compound and a crosslinkable silyl group-containing thiol compound, at least one end of the (meth)acrylic polymer being bonded to a residue, —S—R3 (where R3 represents a group having a crosslinkable silyl group) obtained by removing a hydrogen atom from the crosslinkable silyl group-containing thiol compound.
