Abstract

PURPOSE: To obtain a highly elastic urethane foam, with improved elongation and humid aging resistance, by the reaction of a polymer polyol, a polyether polyol, an ester of a dibasic acid, a polyisocyanate and a foaming agent.
CONSTITUTION: A highly elastic urethane foam is prepared from a polyisocyanate and a foaming agent, by using a polyol mixture, composed of (a) 10W50wt% of a polymer polyol obtained by the polymerization of an ethylenic unsaturated compound in a polyether polyol in the presence of a radical generator, and (b) 50W 90wt% of a polyether polyol of hydroxy value of 25W60, in which the hydroxy group consists of 20W80mol% of primary hydroxy group, and (c) 2W15pts.wt., based on 100pts.wt. said polyol mixture, of a phthalate and/or an ester of an aliphatic dibasic acid.
