摘　　要：采用三步法制备了丙烯酸酯类抗冲改性剂YF-500,通过红外光谱分析、差示扫描量热分析(DSC)、流变性能、力学性能、色差和外观光泽度等与KM355进行了对比测试。结果表明YF-500与KM355具有相同的结构,相近的流变加工性能,相近的玻璃化转变温度、色差和外观光泽度;YF-500的力学性能高于KM355的。YF-500可代替KM355,且性能更优。The acrylate impact modifier YF-500 was prepared by the three-step process,and compared with KM355 through infrared,different scanning calorimetry(DSC),rheological properties,mechanical properties,color difference and appearance gloss tests.The results show that YF-500 and KM355 have the same structure,similar rheological processing properties,similar glass transition temperature,color difference and appearance gloss;the mechanical properties of YF-500 are higher than those of KM355.Therefore,YF-500 can replace KM355 with a better performance.
