Abstract:
A polyurethane foam for shoe soles having an average density of 0.15 to 0.5 g/cm.sup.3, prepared by reacting polyol components comprising:(A) a polyether-polyol A having two or more hydroxyl groups, selected from the group consisting of polyoxypropylene polyols prepared by adding ethylene oxide to the terminal hydroxyl group of a polyoxypropylene polyol and a polyoxytetramethylene glycol prepared by ring-opening polymerization of tetrahydrofuran;(B) a polymer-polyol B comprising a polyether-polyol having two or more hydroxyl groups as a base material and fine polymer particles; and(C) a chain extender,with a polyisocyanate compound in the presence of a blowing agent and a catalyst, wherein the amount of the fine polymer particles is 10 to 30 parts by weight, based on 100 parts by weight of the total amount of the polyether-polyol A and the polymer-polyol B.
