Abstract: In order to prepare thermoplastic polyurethane elastomers (a) organic diisocyanate, (b) polyhydroxyl compounds with molecular weights of 500 to 8,000, and (c) chain extenders with molecular weights of 60 to 400 in the presence of (d) catalysts, and optionally (e) auxiliaries, and/or (f) additives are reacted in two reaction stages at temperatures from 60 DEG C. to 250 DEG C. In the first reaction stage the components are continuously mixed, the reaction mixture is applied to a carrier, preferably a conveyor band of thermoplastic material, and is allowed to react at the reaction temperature until solidified. Subsequently, the solidified reaction mixture is melted in an extruder and the reaction is completed in the second reaction stage.

Abstract: Stable water glass solutions are obtained (A) by mixing a solution of an aqueous alkali silicate solution and alkali hydroxide with a tertiary amine and subsequently oxyalkylating the resultant two-phase reaction mixture with at least one alkylene oxide in such an amount that a uniform solution forms or (B) by oxyalkylating a tertiary amine with at least one alkylene oxide and mixing the resultant reaction mixture with a solution of an aqueous alkali silicate solution and alkali hydroxide. The stable water glass solutions are suitable for the preparation of organo silicate foams. For the preparation of the organo silicate foams, a mixture of the stable water glass solutions and tertiary amino group-containing polyether polyols is reacted with organic polyisocyanates in the presence of catalysts, blowing agents and optionally auxiliaries and additives.
