【摘要】 <正>乙烯-辛烯共聚物(POE)表面能很低,与许多极性材料的相容性差。马来酸酐(MAH) 分子中的氧原子带有丰富的孤对电子,容易同带有空轨道的其他材料共混;同时MAH分子经水解可得到含羧基的活性聚合物,又可同含有羟基、氨基、环氧基等的物质进行反应,生成一系列新型功能聚合物。MAH接枝POE的研究近十几年来开展的非常广泛。紫外光辐照接枝技术具有两个突出的特点:能量低,不会损坏材料的本体性能:成本低,更多还原

【Abstract】 Maleic anhydride grafted Polyolefme-elastomer (POE-g-MAH) were prepared by UV-irradiation and characterized by Infrared spectrum. The effect of UV-Irradiation time on the grafting rate and gel content of POE-g-MAH were studied. The results showed that the optimal duration of UV irradiation was 30s. The grafting rate arrived the highest point (1.977%) and the gel content increased slowly when the irradiation time was 30s.更多还原
