Abstract: The present invention relates to a method for the production of oxazolidinone compounds, comprising the step of slowly reacting an isocyanate compound with an epoxide compound in the presence of a Lewis acid catalyst. The invention further relates to an oxazolidinone compound, obtainable by a method according to the invention, with a colour as determined according to ASTM D1209-05 (2011) of ≦200 and a molar ratio of the oxazolidinone compound to isocyanurate by-product o/i of ≧85/15. Lastly, the invention relates to an oligomeric or polymeric oxazolidinone compound, obtainable by a method according to the invention using an isocyanate compound with two or more NCO groups per molecule and an epoxide compound with two or more epoxy groups per molecule, comprising at least two units derived from the isocyanate compound and at least two units derived from the epoxide compound, with a colour as determined according to ASTM D1209-05 (2011) of ≦200.
