The present invention provides a method for preparing a flame retardant polyepoxy compound in which an oxazolidone ring is formed at an epoxy terminal having excellent flame resistance and heat resistance.n n n The flame-retardant polyepoxy compound in which the oxazolidone ring is formed at the epoxy terminal of the present invention prepared through this suppresses side reactions as much as possible, thereby significantly improving the yield. Through this, it is possible to prepare a flame retardant polyepoxy compound having high glass transition temperature, flame retardant properties, adhesiveness and mechanical chemical properties.n n n In addition, the above-described manufacturing method as an additive of engineering plastics such as ABS, HIPS of the present invention has excellent flame retardancy, heat resistance and physical and chemical properties, PCB substrate requiring insulation material, excellent flame retardancy and thermal stability of electrical and electronic components And various composite materials such as insulating plates, adhesives, coating agents, paints and the like. |
