Abstract
Flame-retardant advanced epoxy resins and cured epoxy resins contain a rigid phosphorus group emanating from a dihydric phenol or naphthol which provides thermal and flame retardant properties. 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.
