description Polyesterurethanes are used in different applications due to their unique combination of the properties like toughness, flexibility, solvent resistance, etc. Nowadays flame retardant properties of polymers are of commercial interest because of their potential use in high performance applications. In the present study attempts have been taken to improve the flame retardant properties of conventional epoxy resin by incorporating phosphorus based polyesterurethane. Polyesterurethane has been synthesized in the laboratory and characterized by chemical and instrumental analysis techniques. Thermal stability and char value of the blends have been determined using thermogravimetric analysis technique. Limiting Oxygen Index (LOI) and UL-94 test methods have been used to determine the flame retardant properties of neat polymer and their blends in film form. Mechanical properties like tensile strength, elongation and impact resistance of the blends have been found out. Polyblend of epoxy resin with phosphorus based polyesterurethane has improved flame retardant properties compare to neat epoxy resin.
