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.

The present invention relates to polyether compounds, active hydrogen compounds and resin-forming compositions composed of the polyols, and methods for producing foams by employing the active hydrogen components. These polyether compounds have a decreased number of moles of added EO thereby maintaining the hydrophobicity and have sufficient reactivity as polyol components of resins, thereby having high reaction rates. Therefore, it is possible to provide resins having excellent resin properties (tensile strength, flexural strength, water-absorption swelling ratio, etc.).
