Abstract

PURPOSE: To prepare a polyurethane having improved elasticity and heat resistance, by using a composition consisting of a polymer polyol and a rubber latex, as a polymeric polyol component.
CONSTITUTION: A polyurethane is prepared by reacting (A) an organic polyisocyanate compound, with (B) a polymeric polyol compounent comprising a polyol dispersion composition prepared by eliminating water from a mixed dispersion composed of (a) a polyether polyol and (b) a rubber latex, and if necessary, (C) an active hydrogen-containing low molecular compound (e.g. tolylenediamine, etc.) and (D) a blowing agent (e.g. halogen-substituted aliphatic hydrocarbon, etc.). The preferable amount of (B) is 2W60 parts by weight (solid content) on the basis of 100 parts by weight of (A).
