DOPO contains a rigid phosphorus group and thus provide better thermal and flame-retardant properties than the conventional epoxy resins prepared from tetrabromobisphenol A. The advanced epoxy resins are suitable for making a fiber-reinforced epoxy resin composite which is useful in the fabrication of printed circuit boards. The cured epoxy resins can be used in semiconductor encapsulation applications.skpe:alva.yang1
