Abstract: The hard polyurethane foam is prepared by reaction of (a) at least one polyisocyanate with (b) at least one compound having at least two H atoms reactive to isocyanate groups in a closed mold, where polyisocyanate (a) is a polyisocyanate mixture (a1) containing (wt.%): a mixture of diphenylmethane diisocyanate (I) and polymethylenepolyphenylene polyisocyanate (II) of NCO content 30-32,a two-core isomer content of 46-49, a content of 3-core isomers of 22-25, a content of 4-core isomers of 6-8, and an isomer distribution of the 2-core content of 41-45 of the 4,4- and 4,4'- isomers and 2-5 of the 2,4- and 2,4'- isomers, relative to the mixture of I and II.

Abstract: Flexible polyurethane foams having low compressive strength and relatively good tensile strength are prepared by reacting a) a block polyoxypropylenepolyoxyethylenepolyol 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 polyoxypropylenepolyoxyethylenepolyol mixtures with bi- and/or trifunctional polyoxypropylenepolyoxyethylenepolyols 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.

Abstract: The invention relates to a process for the production of flexible, soft polyurethane foams having viscoelastic, structure borne soundproofing properties in a temperature range of from -20 DEG C to +80 DEG C, by reacting a) a polyoxyalkylene-polyol mixture containing ai) a block polyoxypropylene-polyoxyethylene-polyol mixture having a hydroxyl number of from 14 to 65 and containing from 2 to 9 % by weight, based on the weight of the polyoxypropylene units, of terminally bonded ethylene oxide units, and prepared by anionic polymerisation at elevated temperature of 1,2-propylene oxide onto an initiator molecule mixture having a mean functionality of from 2.3 to 2.8 comprising water and glycerol and/or trimethylolpropane, and polymerisation of ethylene oxide onto the resultant polyoxypropylene adduct, and aii) at least one difunctional and/or trifunctional polyoxypropylene-polyoxyethylene-polyol containing from 60 to 85 % by weight, based on the total weight of polymerised alkylene oxide units, of oxyethylene units, and having a hydroxyl number of from 20 to 80, and b) optionally 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 optionally f) assistants and/or additives, and to the polyoxyalkylene-polyol mixtures (a) which can be used for this purpose.
