摘要： The present invention relates to a method for the production of oxazolidinone compounds with low colour intensity, comprising the step of reacting an isocyanate compound with an epoxide compound in the presence of a catalyst which is free of halide anions. The invention further relates to a method for the production of oligooxazolidinone and/or polyoxazolidinone compounds, comprising the step of reacting a polyisocyanate compound with a polyepoxide compound in the presence of said catalyst. The invention further relates to oligooxazolidinone and/or polyoxazolidinone compounds with low colour intensity, obtainable by a method according to the invention.

摘要： The present invention relates to a method for the production of polyoxazolidinone compounds, comprising the step of reacting an isocyanate compound, preferably a diisocyanate compound with an epoxide compound, preferably a diepoxide compound. The invention further relates to a polyoxazolidinone compound obtainable by said method, a polymeric resin obtainable by reacting a polymeric compound according to the invention with a cross linking compound and the use of a polymeric resin according to the invention as a coating, additive and composite material.
