Abstract
PURPOSE: To prepare a polyurethane having excellent curability and rigidity, by using a polymer polyol prepared from an amine-type polyether polyol and an ethylenic unsaturated monomer, as a portion of the polyol component.
CONSTITUTION: A polyurethane is prepared by the reaction of a mixture comprising (A) an organopolyisocyanate (e.g. tolylene diisocyanate), (B) a low molecular polyol (e.g. 1,4-butanediol), (C) a polymer polyol prepared from an amine-type polyether polyol having terminal polyoxyethylene chains, and an ethylenic unsaturated monomer (e.g. a polyether polyol prepared by addition reaction of propylene oxide and ethylene oxide to triethanolamine, is reacted with acrylonitrile), and if necessary (D) a blowing agent.
EFFECT: The amount of the catalyst is reduced, and the heat resistance of the polyurethane is kept high.
