Abstract

PURPOSE: To obtain a polyurethane having improved moldability and appearance, by reacting a compound, having active hydrogen atoms, and consisting of a polyol and modified polysiloxane with an organic polyisocyanate by the reaction injection molding method.
CONSTITUTION: (A) A compound, containing active hydrogen atoms, and consisting of (i) a high-molecular weight polyol, e.g. polyester-polyol, (ii) a low- molecular weight polyol, e.g. ethylene glycol, and (iii) a modified polysiloxane having one or more active hydrogen atoms reactive to an organic polyisocyanate in the molecule is reacted and molded with (B) the organic polyisocyanate, e.g. hexamethylene diisocyanate, by the reaction injection molding method to give the aimed polyurethane. A polysiloxane, e.g. polyoxyalkylene-, carbinol-, amine- or carboxyl-modified polysiloxane is preferred as the component (iii).
