Samenvatting

The present invention relates to a process for preparing polyurethanes in which (a) polyisocyanate, (b) polymeric compounds having groups reactive toward isocyanates, (c) catalysts, and optionally (d) blowing agents, (e) chain extenders and/or crosslinkers, and (f) auxiliaries and/or additives are mixed to give a reaction mixture and the reaction mixture is left to react to give the polyurethane, wherein the polymeric compounds (b) include a polyesterol (bl) obtainable by polycondensation of an acid component with an alcohol component, where the acid component comprises malonic acid and/or derivatives thereof and the alcohol component an aliphatic dialcohol having 4 to 12 carbon atoms. The present invention further relates to a polyurethane obtainable by such a process and to use in closed spaces.
