Abstract: The invention relates to a composite element comprising A) at least one top layer of polyvinyl chloride or a polyvinyl chloride-containing polymer mixture, and B) a preferably semi-rigid or rigid polyurethane foam, where the top layer (A) or the polyurethane foam (B) or both constituents (A) and (B) contain units of an alpha , beta -olefinically unsaturated polyester having a molecular weight factor of from 150 to 3000 per double bond, to a process for the production of composite elements of this type, and to liquid, urethane group-containing polyisocyanate mixtures based on diphenylmethane diisocyanates and higher homologues thereof and alpha , beta -olefinically unsaturated polyesters for the preparation of polyurethane foams (B).

Abstract: The invention relates to a process for the production of mouldings having a compact outer layer and a cellular core, for example soft, flexible shoe soles, having a density of from 0.4 to 1.0 g/cm , by reacting a) organic and/or modified organic polyisocyanates with b) at least one high-molecular-weight compound containing at least two reactive hydrogen atoms and, if desired, c) low-molecular-weight chain extenders and/or crosslinking agents, in the presence of d) low-boiling aliphatic and/or cycloaliphatic hydrocarbons having 4 to 8 carbon atoms in the molecule, preferably pentanes, as blowing agent, e) catalysts and, if desired, f) assistants and/or additives. l

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.
