A process for producing thermoplastic polyoxazolidinone, comprising (i) reaction of a diisocyanate compound (A) with a bisepoxide compound (B) in the presence of a catalyst (C) and a compound (D) in a solvent (E) forming an intermediate compound (F) and (ii) reaction of a compound (G) with the intermediate (F) formed in step (i), where the bisepoxide compound (B) comprises isosorbide diglycidyl ether, where compound (D) is ≥1 compounds selected from monofunctional isocyanate and monofunctional epoxide, and where compound (G) is an alkylene oxide. The experimental process involved the reaction of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione(cas: 5455-98-1).Category: amides-buliding-blocks
