Abstract

The present disclosure relates to a process for producing polyurethanes including mixing (a) polyisocyanate, (b) polymeric compounds having isocyanate-reactive groups, (c) catalysts and optionally (d) blowing agents, (e) chain-extending and/or crosslinking agents and (f) auxiliaries and/or additives to afford a reaction mixture and reacting the reaction mixture to afford polyurethane. The polymeric compounds having isocyanate-reactive groups (b) are a polyesterol (b1) obtainable by polycondensation of an acid component with an alcohol component. The acid component includes malonic acid and/or derivatives thereof and the alcohol component includes an aliphatic dialcohol having 4 to 12 carbon atoms. The present disclosure further relates to a polyurethane obtainable by such a process and to a method of using in enclosed spaces.
