Abstract: Polyurethanes are prepared by reaction of: (a) at least one polyisocyanate with (b) at least two compounds having at least two hydrogen atoms reactive to isocyanates, by insertion of the liquid starting components into a mold on the surface of a building component, and finally insertion of the building component with the starting components into a closed mold. The compounds with at least two hydrogen atoms reactive to isocyanate groups are selected from 1-5C, preferably 2C dialkyltoluylenediamines in the alkylene chain and 2,2'-dimethyl-4,4'-methylene bis(cyclohexylamine). An Independent claim is included for a polyurethane prepared as above.

Abstract: A process for preparation of a hard polyurethane integral foam material by reaction of (a) at least one polyisocyanate with (b) at least one compound having at least two hydrogen atoms reactive to isocyanate groups in a closed mold, where the compounds with at least two isocyanate reactive hydrogen atoms consist of a mixture of at least one polyether alcohol and at least one polyester alcohol is new. An independent claim is included for a hard polyurethane integral foam material obtained as above.

Abstract: Flexible polyurethane foams having low compressive strength and relatively good tensile strength are prepared by reacting a) a block polyoxypropylene-polyoxyethylene-polyol mixture which has a hydroxyl number of from 14 to 65, contains from 2 to 9% by weight, based on the weight of the polyoxypropylene units, of ethylene oxide units bonded in the terminal position and is prepared by anionic polymerization of the alkylene oxides with an initiator mixture having an average functionality of from 2.3 to 2.8 and consisting of water and glycerol and/or trimethylolpropane, or a mixture of these block polyoxypropylene-polyoxyethylene-polyol mixtures with bi- and/or trifunctional polyoxypropylenepolyoxyethylene-polyols having a hydroxyl number of from 20 to 70, and b) if required, low molecular weight chain extenders with c) organic and/or modified organic polyisocyanates in the presence of d) catalysts, e) blowing agents, preferably water, and if required, f) assistants and/or additives.
