Zusammenfassung:Described herein is a process for preparing a polyurethane-polyisocyanurate compound by mixing a) at least one polyisocyanate; b) a mixture (M); c) at least one compound including one or more epoxide groups; d) at least one aliphatic polyol (P1) having a high weight average molecular weight; e) at least one polyol (P2) having a low weight average molecular weight; f) at least one compatibilizer; and, optionally, g) fillers and further additives to form a reaction mixture (RM); and reacting the mixture (RM) to give the polyurethane-polyisocyanurate compound. Also described herein are a polyurethane-polyisocyanurate compound obtainable by the process and a method of using the polyurethane-polyisocyanurate compound for producing bodywork components for vehicles.
