    摘要： Thermosetting resins are produced by blending 1 equivalent of a polyoxazolidone terminated by two vicinal epoxy groups and containing at least two oxazolidone rings with at least 1 equivalent of a polyfunctional isocyanate compound, adding 0.01 to 10% by weight of a catalyst which forms isocyanurate rings and oxazolidone rings based on the total amount of the polyoxazolidone and the isocyanate compound, and then heating the resulting composition to polymerize the composition by forming isocyanurate rings and oxazolidone rings. The resin compositions have excellent mechanical properties, and particularly excellent flexibility, and excellent thermal resistance.
