2. Description of the Related Art Conventionally, various curable compositions have been developed which are cured to form a rubber-like substance. Among them, those obtained by crosslinking an organic polymer having one or more alkenyl groups in one molecule with a compound having at least two hydrosilyl groups in one molecule are excellent in fast-curing property and deep-curing property. Known as curing system. However, when the polyoxypropylene-based polymer is applied to a curing system utilizing the above-mentioned hydrosilylation, when the polyoxypropylene-based polymer having an alkenyl group has a low molecular weight, it exhibits a good rubber-like elastic behavior. When a cured product cannot be obtained and the molecular weight distribution is wide, there is a problem that the viscosity before curing becomes high and handling becomes difficult.
