On May 7, 2020, Koopmans, Carsten; Laemmerhold, Kai; Guertler, Christoph; Frick-Delaittre, Elena; Wolf, Aurel; Simon, Joachim; Wang, Min; Thiel, Daniel; Leitner, Walter published a patent.HPLC of Formula: 5455-98-1 The title of the patent was Method for the production of thermoplastic polyoxazolidinone polymers. And the patent contained the following:
The invention relates to a process for producing thermoplastic polyoxazolidinones, 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), characterized in that, the bisepoxide compound (B) comprises isosorbide diglycidyl ether, the catalyst (C) is selected from the group consisting of alkali halogenides and earth alkali halogenides, and transition metal halogenides, the compound (D) is selected from the group consisting of monofunctional isocyanate, monofunctional epoxide, and wherein the process comprises: (a) placing the solvent (E) and the catalyst (C) in a reactor to provide a mixture; and (b) adding the diisocyanate compound (A), the bisepoxide compound (B), and the compound (D) to the mixture resulting from step (a). Thermoplastic polyoxazolidinone obtainable by the inventive process is also claimed. 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
