Abstract

Cellular polyurethanes are obtained by reacting a polyalkylene ether of Mol. wt. at least 400 and having terminal -OH and/or -NH2, water, an organic polyisocyanate, and an organo silicon compound having at least one hydroxyl group. Suitable organosilicon compounds are silanols and siloxanes having one or more -OH, e.g. diethyl- and diphenyl-silanediol; triphenyl silanol; tetramethyl, tetraethyl and tetraphenyl disiloxanediol; or an ester formed from a silanol or a siloxane and adipic or succinic acid. The polyethers described are the usual ones (but include polythioethers) together with the poly addition products of polyacetals and olefines of the type disclosed in Specification 866,323. They may be used in conjunction with other polyfunctional compounds. The polyisocyanates are the usual ones, and they may contain chlorine, nitro or alkoxy substituents. The trimerized products of monomeric diisocyanates and the reaction product of a polyol with a diisocyanate can also be used. A prepolymer may be formed, or not, as desired. A tertiary amine catalyst may be used. Specifications 769,680 and 769,682 also are referred to.ALSO:Cellular polyurethanes are obtained by reacting a polyalkylene ether of Mol-wt. at least 400 and having terminal-OH and/or -NH2, water, an organic polyisocyanate, and an organo silicon compound having at least one hydroxyl group.
