【Abstract】 Compatibility, mechanical properties and heat resistance of ABS/St co NPMI blends were investigated by means of TBA, tensile measurements and heat resistance measurement. The TBA results indicate that the blends are partly compatibilizing system. Tensile measurements show that the tensile modulus increase with the addition of styrene co N phenylmaleimide(St co NPMI) copolymer, and the tensile strength is almost not changed. Heat resistance measurement indicates that Vicat Softening Points increase about 10 ℃ when the content of St co NPMI copolymer is 15%.更多还原
