    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.

    Abstract: The present invention relates to a method for producing a molded body (MB) comprising the production of a thermoplastic polyurethane, the production of a molded body (MB*) from the thermoplastic polyurethane, heating the molded body (MB*) to a temperature below the temperature at which there is permanent deformability of the molded body (MB*), and above the switching temperature of the thermoplastic polyurethanes, elongating the heated molded body (MB*) with obtention of a molded body (MB), and cooling the molded body (MB) to a temperature below the switching temperature of the thermoplastic polyurethane, and the molded body obtained or obtainable by such a method. The present invention further relates to a thermoplastic polyurethane with shape memory and the use of a thermoplastic polyurethane for producing a molded body with shape memory effect in a temperature range from 0° C. to 130° C.
