    摘要： A reaction product formed between an epoxy resin, a phenol compound such as bisphenol or the like and an isocyanate compound contains oxazolidone rings and it is a polymeric epoxy resin. Herein is provided an epoxy resin composition comprising said reaction product and a curing agent.The said reaction product contains oxazolidone rings and epoxy groups, and is excellent in heat resistance and adhesive property. Further said reaction product is made into a polymer by the use of the bisphenol compound and at the same time it contains oxazolidone rings; it is excellent in toughness and water resistance. When a tetrabromobisphenol is used as the bisphenol compound, flame retardance is also good.Accordingly, the epoxy resin composition of the present invention is excellent in heat resistance, toughness, adhesive property and water resistance. When a brominated compound is used as the phenol compound, the epoxy resin composition of the invention exhibits an excellent flame retardance.
