Title: Improvements in or relating to the manufacture of polymeric materials
Inventor: HAGGIS GEOFFREY ARTHUR
IPC: C08J9/30
Filed: 1962-11-23
Abstract: Foamed polyurethane material is made by forming a reaction mixture containing an organic polyisocyanate, a hydroxyl group-containing polymer and a foam-stabilizing agent, foaming the mixture by incorporating therein an inert gas at a pressure substantially equal to that of the surrounding atmosphere and finally completing the polyurethane-forming reaction.  The inert gas is chosen so that it has a rate of diffusion through the polymer no greater than that of air.  Gases specified are air, nitrogen, oxygen, argon, helium, halogenated hydrocarbons such as methyl or ethyl chloride and dichlorodifluoromethane. The inert gas can be incorporated in the reaction mixture either continuously or discontinuously by known methods.  Hydroxyl group-containing polymers include polyesters and polyesteramides made from dicarboxylic acids, such as succinic, adipic, suberic, azelaic, sebacic, dilinoleic, phthalic, isophthalic and terephthalic acids, and polyhydric alcohols such as glycols, e.g. ethylene glycol, 1:3-butylene glycol, 2:2-dimethyl trimethylene glycol, trimethylol ethane and glycerol, in the presence of minor proportions of diamines and amino alcohols.  Polyethers which may be used include hydroxyl-ended polymers and co-polymers of cyclic oxides, e.g. 1:2-alkylene oxides, oxacyclobutane, substituted oxacyclobutanes, and tetrahydrofuran. Foam stabilizing agents and catalysts are also used in the reaction mixture. The foaming produced by the incorporation of the inert gas may be augmented by the inclusion of a conventional blowing agent such as a hydrocarbon or by the chemical reaction between organic polyisocyanate and water.
