| 摘 要： | 在转矩流变仪中通过熔融接枝反应制备了EPDM-g-GMA，将其与聚丙烯（PP）在双螺杆挤出机中熔融共混。用化学滴定法测定EPDM-g-GMA的接枝率；用红外光谱对接枝物进行表征；用SEM观察共混物的形态。通过对PP／（EPDM-g-GMA）共混物的形态结构和力学性能的研究，发现随着EPDM-g-GMA的含量或温度的增加，PP／（EPDM-g-GMA）共混物的缺口冲击强度相应提高，而拉伸强度降低，断裂伸长率相应增加。

| Abstract: | Copolymer EPDM-g-GMA was prepared by grafting glycidyl methacrylate(GMA)on to EPDM in torsion rheometer.PP with EPDM-g-GMA was blended in the twin-screw extruder.The grafting yield of EPDM-g-GMA copolymers was determined by turning over titration measure,whether the grafting of EPDM-g-GMA copolymers depends on FTIR measurements.The morphology and mechanical properties of PP blended with EPDM-g-GMA were studied.It was found that with increase of the EPDM-g-GMA content or increase of temperature,the Izod notc... |
