Abstract: Synthetic crystalline aluminosilicate zeolites are crystallized from an aqueous reaction mixture comprising sources of alkali metal oxide, silicate, aluminate and an ionene or ionomer which contains positively charged nitrogen atoms in such quantity as to satisfy some of the cationic sites of the eventual zeolite. The presence in the reaction mixture of such a polymer serves to direct crystallization of the zeolite, giving rise to the formation of large pore zeolites under conditions where small pore zeolites would otherwise result, to the formation of more siliceous zeolite than would otherwise result, and to the formation of certain species of zeolite essentially free of stacking faults, the crystallization of which has not heretofore been possible.

Abstract: A liquid-filled polyurethane elastomer gel is fabricated from water, organic glycol and a polyisocyanate prepolymer. The prepolymer is formed from organic diisocyanate and organic diol or triol having a molecular weight of 3,000 to 10,000 and containing at least 40 percent by weight ethylene oxide adducts. The prepolymer is mixed with 3 to 20 times its weight of aqueous reactant including 25 to 65 percent by weight water and 75 to 35 percent by weight organic polyol. The resulting stable gel contains aqueous solutions of emulsions dispersed therein as small droplets comprising 75 to 95 percent of the weight of the resulting article. The liquid-filled polyurethane elastomer gel can be cast into shapes or can be formed into globs of random shape.
