Abstract

PURPOSE: To obtain a highly elastic polyurethane foam, with improved wet-heat aging resistance, by the reaction of a polymer polyol, a polyether polyol, an alkanolamine, a polyisocyanate and a foaming agent.
CONSTITUTION: A highly elastic polyurethane foam is prepared from a polyisocyanate and a foaming agent, by using a polyol mixture composed of (a) 10W50wt% of a polymer polyol of hydroxy value of 25W40, obtained by the polymerization of an ethylenic unsaturated compound in a polyether polyol in the presence of a free- radical catalyst, and (b) 50W90wt% of a polyether polyol of hydroxy value of 40W 50, in which the hydroxy group consists of 20W80mol% of primary hydroxy group, and (c) 0.5W3pts.wt., based on 100pts.wt. of said polyol mixture, of an alkanolamine.
