Patent number: 4358548Abstract: For forming synthetic cellular materials, gas is generated by the reaction of an isocyanate and a hydroperioxide. The reactants produce a novel polymeric amine oxide foam. When the reactants are introduced to a base resin, cellular foam products (densities throughout the 50 to 2 lbs/ft.sup.3 range), extended resin products of even higher densities, and non-shrink resinous solids (with microcellular distribution of gas) can be obtained. When employed in resins curable with hydroperoxide, a small fraction of the hydroperoxide interacts with a promoter and serves to cure the resin while the larger fraction reacts earlier with the isocyanate to evolve gas before the gellation state of the base resin is reached. The foaming agent can be made commercially available as a premixture of isocyanate and appropriate surfactant for the hydroperoxide reaction. By mixing with low hydroxyl and carboxyl base resin, long pot life is obtainable.Type: GrantFiled: January 14, 1980Date of Patent: November 9, 1982Assignee: Whitney & Company, Inc.Inventor: Glen W. Saidla
