摘　　要：采用熔融接枝法在聚烯烃弹性体(POE)上分别接枝三种不同的反应性单体马来酸酐(MAH)、丙烯酸(AA)、甲基丙烯酸环氧丙酯(GMA),制备了POE-g-GMA,POE-g-MAH,POE-g-AA,考察了三种不同反应基团接枝的POE对PET的增韧效果。采用傅立叶变换红外光谱(FTIR)证实三种反应单体成功接枝到POE分子链上。结果表明,PET/POE-g-GMA共混物的冲击强度、相容性明显高于PET/POE-g-AA与PET/POE-g-MAH共混物,熔体流动速率明显降低。POE-g-AA与POE-g-MAH不能有效增韧PET,而POE-g-GMA是PET的有效增韧剂。Reactive monomers such as acrylic acid （AA）, maleic anhydride （MAH）and glycidyl methacrylate （GMA）were grafted onto polyolefinic elastomer（POE） by melt blending to prepare POE-g-GMA, POE-g-MAH, POE-g-AA. The different reactive groups functionalized POE elastomers used as modifiers to toughen polyethylene terephthalate（PET） were investigated. Fourier transform infrared spectroscopy（FTIR） results show that these monomers were introduced onto POE. The results show that impact strength and compatibility are improved obviously in PET/POE-g-GMA blends than in PET/POE-g-AA and PET/POE-g- MAH. The melt flow rate of blends decrease obviously in PET/POE-g-GMA blends. POE-g-AA and POE-g-MAH are ineffective for toughening PET, but POE-g-GMA is effective for toughening PET.
