摘要： A method for producing a molded product of integral-skin polyurethane foam, which comprises reacting and curing (1) a high molecular weight polyol comprising, as the main component, a polyoxyalkylene polyol having, as the main constituent, oxyalkylene groups of at least 3 carbon atoms and oxyethylene groups at its molecular terminals with the overall oxyethylene group content being not higher than 15% by weight and having a hydroxyl value of not higher than 80, (2) a crosslinking agent containing a compound having an aromatic nucleus and at least two active hydrogen-containing groups selected from the group consisting of hydroxyl groups, primary amino groups and secondary amino groups, and (3) a polyisocyanate, in a mold in the presence of a catalyst and a hydrogen atom-containing halogenated hydrocarbon foaming agent.
