    Abstract: The present invention relates to a compact polyurethane having a density of ≥ 850 g/l, which is obtained or can be obtained by reaction of at least the components: i) polyisocyanate composition; ii) polyol composition, comprising at least one polyether polyol (ii.1), which is obtained or can be obtained by reaction of ii.1.1) a polyol starter with a functionality of 3 to 6 with ii.1.2) propylene oxide and/or butylene oxide, in the presence of a boron-based fluorine-containing Lewis acid catalyst (ii.1.3), wherein the polyether polyol (ii.1) has an equivalent molecular weight of 50 to 150 g/mol, ii.1.4) optionally further auxiliary materials and/or additives. The invention further relates to a method for producing a compact polyurethane of this type and to compact polyurethanes which are or can be obtained by this method. The invention additionally relates to the use of a compact polyurethane of this type having a density of ≥ 850 g/l for the production of a fibre-reinforced composite material. The invention likewise relates to a corresponding fibre-reinforced composite material and a method for producing a fibre-reinforced composite material of this type.

    Abstract: The present invention relates to a process for producing polyurethanes having reduced aldehyde emission. According to the invention, a CH-acid compound is added to the reaction mixture to produce the polyurethane, said compound comprising one or more alkylene oxide moieties. The present invention further relates to polyurethanes which have been produced by such a process and to the use of such polyurethanes in the interior of means of transport.
