Curable composition

Abstract

Abstract PURPOSE:A composition having improved adhesiveness after curing, preventing expansion in volume, easily treatable free from temperature dependence of viscosity, obtained by blending polybutadiene or a copolymer consisting essentially of butadiene with a specific polyether polymer. CONSTITUTION:(A) 100pts.wt. modified or unmodified polybutadiene or copolymer consisting essentially of butadiene is blended with (B) 1-1,000pts.wt. polyether polymer containing at least one hydrolyzable silicon group in the molecule and 300-15,000 molecular weight. The component A used has a group such as hydroxyl group, carboxyl, or ester, etc. or is hydrogenated. The component B used consists essentially of propylene oxide. The composition is preferably blended with a small amount of a curing catalyst.
