Patent ID: 7838586

Claim:
A resin composition comprising: an oxyalkylene polymer (A) containing a hydrolyzable silicon group and being prepared by ring-opening polymerization of an alkylene oxide using a cobalt-containing double metal cyanide complex catalyst in the presence of a compound that serves as an initiator and that has an active hydrogen-containing group that can react with the alkylene oxide; an acrylic polymer and/or a mercapto group-containing compound (B), the acrylic polymer containing a hydrolyzable silicon group and being prepared by radical polymerization of a monomer including an alkyl (meth)acrylate containing an alkyl group having 1 to 30 carbon atoms in the presence of a mercapto group-containing compound; and a reductant (C) which is at least one selected from ascorbic acid and derivatives thereof.
