摘要： The present invention relates to a method for producing a cured composition, which has at least one oxazolidinone ring and at least one isocyanurate ring and is crosslinked thereby, starting from a liquid reaction mixture comprising: (a) at least one liquid, aromatic epoxy resin; (b) at least one liquid, aromatic polyisocyanate; and (c) a catalyst composition; relative to the at least one polyisocyanate, the at least one epoxy resin is used in amounts such that the molar equivalent ratio of epoxide groups to isocyanate groups is at least 0.4; and curing the reaction mixture to give a cured polymer composition comprising at least one oxazolidinone ring and at least one isocyanurate ring, and also to the cured compositions obtainable by these methods.
