Abstract
A process for the production of molded articles of flexible polyurethane foam by the interaction of an organic polyisocyanate with a polyol which is a polyoxypropylene having chain end groups derived from ethylene oxide, characterized in that the polyisocyanate is one having 2, 3 or 4 benzene rings, each carrying at least one isocyanate group, the rings being linked together by means of methylene groups, and the reaction mixture containing the polyol and the polyisocyanate is fed into a mold and left to cure without the application of heat.
