以过氧化苯甲酰 (BPO)为引发剂 ,用固相接枝共聚的方法制备高密度聚乙烯接枝马来酸酐 (HDPE g MAH) ;用红外光谱法检测接枝产物的生成 ;通过差量法计算接枝率 ,着重探讨了各因素对接枝率的影响。
High-density polyethylene grafted maleic anhydride (HDPE g MAH) was prepared by solid-phase graft copolymerization using benzoyl peroxide (BPO) as initiator. The grafting product was detected by infrared spectroscopy. Gravimetric method to calculate the grafting rate, focusing on the various factors on the grafting rate.
