    Abstract: Described herein are processes for producing moldings comprising oxazolidinone groups, where polyisocyanate (a) is mixed with at least one organic compound (b) having two or more epoxide groups, at least one catalyst (c) for the isocyanate/epoxide reaction, and optionally auxiliary and additive materials (d) to form a reaction mixture, which is introduced into or applied to a mold and reacted to give moldings including oxazolidinone groups, where the catalyst (c) for the isocyanate/epoxide reaction includes a compound of the general formula [M(R1)(R2)(R3)(R4)]+ [X In]−, where M is a nitrogen atom or a phosphorus atom, R1, R2, R3 and R4 are an organic radical, X is fluorine, chlorine, bromine or iodine, I is iodine, and n stands for rational numbers from 0.1 to 10.
