Abstract
Abstract A curing composition useful as a pressure sensitive adhesive, a sealant, a paint, etc. having excellent weatherability and adhesive property as well as excellent initial tackiness and heat resistance which contains as effective components (A) a polyether having in one molecule at least one functional group selected from a reactive silicon-containing group and an olefin group and (B) at least one specific vinyl polymer such as a homopolymer or copolymer with or without reactive silicon-containing groups in the side chains or an acrylate and/or methacrylate polymer with reactive silicon-containing groups in the polymer ends. The product obtained by polymerizing a monomer or monomers for constituting the component (B) in the presence of the polyether (A) is also useful as the effective component of the curing composition.
