On February 22, 2018, Weber, Anna; Rangheard, Claudine; Kessler, Michael; Leitner, Walter; Guertler, Christoph; Koopmans, Carsten; Mueller, Thomas Ernst published a patent.Recommanded Product: 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione The title of the patent was Process for the synthesis of polyoxazolidinone compounds. And the patent contained the following:
The invention relates to a method for the production of polyoxazolidinone compounds, comprising reacting an isocyanate compound (A) with an epoxide compound (B) in the presence of a catalyst (C), wherein the isocyanate compound (A) comprises a isocyanate compound (A1), comprising at least two isocyanate groups (I1 ≥ 2), preferred two isocyanate groups (I1 = 2), wherein the epoxide compound (B) comprises a epoxide compound (B1) and an epoxide compound (B2) different from the epoxide compound (B1), wherein the epoxide compound (B1) comprising at least two terminal epoxide groups (F1 ≥ 2), preferred two terminal epoxide groups (F1 = 2), linked together by a linking group (L1), and the epoxide compound (B2) comprising at least two terminal epoxide groups (F2 ≥ 2), preferred two terminal epoxide groups (F2 = 2), linked together by a linking group (L2 ), wherein the linking group (L2) comprises acyclic and covalent bonds to each other free of conjugated multiple bonds within the main chain, wherein the epoxide compound (B2) is present in the epoxide compounds B1 and B2 in an amount of ≥ 0.01 – < 10 mol%, preferred 1 - 9 mol%, more preferred 3 - 8 mol% based on the molar ratio the terminal epoxide groups in the epoxide compound (B1) and of the sum of the terminal epoxide groups in the epoxide compound (B1) and terminal epoxide groups in the epoxide compound (B2). Polyoxazolidinone compound, obtainable by the inventive method, is also claimed. Spun fiber, comprising a polyoxazolidinone compound, is also concerned. Textile, comprising a spun fiber, is also directed. The experimental process involved the reaction of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione(cas: 5455-98-1).Recommanded Product: 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione
