Abstract The invention is related to a process for producing an isocyanate-group terminated polyoxazolidinone comprising the copolymerization of a polyisocyanate compound (A) with two or more isocyanate groups with a polyepoxide compound (B) with two or more epoxy groups in the presence of a specific catalyst (C), wherein the molar ratio of the isocyanate groups of the polyisocyanate compound (B) to the epoxy groups of the polyepoxide compound (A) is larger than 2:1 and less than 25:1. The invention is also related to the resulting isocyanate-group terminated polyoxazolidinones.
