Abstract: Disclosed herein is a method for producing a thermally stable thermoplastic polyoxazolidinone compound including the steps of mixing (a) at least one diisocyanate, (b) at least one organic compound having two epoxide groups, (c) at least one catalyst, catalyzing the formation of oxazolidinone groups and (d) optionally at least one solvent to form a polyoxazolidinone, and contacting this polyoxazolidinone with carbon dioxide. Further disclosed herein are a thermoplastic polyoxazolidinone, obtained from the disclosed method, a method for producing a molded part including the step of melting the polyoxazilodinone, introducing the melt into a mold, cooling the polyoxazolidinone in the mold to temperatures below its melting point and demolding the obtained molded part, and a molded part obtained by such a method.

Abstract: A process for preparing a polymer containing a structural element involves: (a) providing an uretdione of formula (I), and (b) opening a ring of the uretdione at a temperature greater than 50° C. and in the presence of a catalyst composition containing at least one catalyst, to obtain the polymer. In the element —N—C(═O)—X2, X2 is a derivative of the group X1 reactive towards isocyanates: The polymer containing the element —N—C(═O)—X2—obtained from the process is useful. A method for modifying polymers which have reactive groups towards isocyanate groups involves: (i) providing a polymer having at least one functional group reactive towards isocyanate groups; (ii) providing an uretdione, of formula (II); and (iii) reacting the polymer with the uretdione at a temperature of more than 50° C. in the presence of a catalyst composition containing at least one catalyst. The modified polymer obtained according to the method is useful.
