    Abstract: A process for producing a polymer foam comprises reacting components A to C in the presence of component D and optionally E or an isocyanate-functional prepolymer of components A and B with component C in the presence of component D and optionally component E, the total amount of which is 100 wt%, (A) 35 to 65 wt% of at least one polyisocyanate component A, wherein 10 to 100 wt% of component A is a condensation product comprising polyimide groups and resulting from condensing at least one polyisocyanate component with at least one polycarboxylic acid having at least 3 COOH groups per molecule or with the anhydride of said acid, (B) 5 to 50 wt% of at least one polyol component B, (C) 1 to 59 wt% of at least one polycarboxylic acid component C, and (D) 0.01 to 3 wt% of at least one Lewis base component D, (E) 0 to 5 wt% of at least one foam stabilizer component E, wherein the reaction takes place with a release of carbon dioxide.

    Abstract: The invention provides a thermoplastic polyurethane having at least one plasticizer, with at least one first plasticizer (i) being based on a glycerol, and at least one hydroxyl group of the glycerol being esterified with a monocarboxylic acid (ii) which contains 1, 2, 3, 4, 5 or 6 carbon atoms, more preferably 2, 3 or 4 carbon atoms and very preferably 2 carbon atoms. The invention further encompasses a process for preparing the thermoplastic polyurethane having the plasticizer (i), a method for coating products with this thermoplastic polyurethane, the use of the thermoplastic polyurethane, and the use of plasticizers based on glycerol for thermoplastic polyurethane.
