On March 21, 2019, Koopmans, Carsten; Guertler, Christoph; Wolf, Aurel; Frick-Delaittre, Elena; Laemmerhold, Kai; Rangheard, Claudine; Breuer, Timo published a patent.HPLC of Formula: 5455-98-1 The title of the patent was Method for the production of thermplastic polyoxazolidinone polymers. And the patent contained the following:
A process for producing thermoplastic polyoxazolidinone comprising copolymerization 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), wherein the catalyst (C) is selected from the group consisting of alkali halogenides and earth alkali halogenides, and transition metal halogenides, compound (D) is selected from the group consisting of monofunctional isocyanate, monofunctional epoxide, and wherein the process comprises step (α) of placing the solvent (E) and the catalyst (C) in a reactor to provide a mixture, and adding the diisocyanate compound (A), the bisepoxide compound (B) and the compound (D) in step (β) to the mixture resulting from the step (a).The invention is also related to the resulting thermoplastic polyoxazolidinone. The experimental process involved the reaction of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione(cas: 5455-98-1).HPLC of Formula: 5455-98-1
