为了在超高分子量聚乙烯(PE-UHMW)大分子链上引入极性基团，采用固相接枝法制备PE-UHMW接枝马来酸酐(MAH)(PE-UHMW-g-MAH)，以二甲苯、十氢萘和白油为界面剂，过氧化苯甲酰(BPO)为引发剂，用接枝单体MAH对PE-UHMW进行接枝改性。通过傅立叶变换红外光谱(FTIR)、酸碱滴定等测试方法对PE-UHMW-g-MAH进行表征。讨论了界面剂种类及用量、引发剂及接枝单体用量、反应时间、反应温度等因素对反应接枝率的影响。最终选用二甲苯作为界面剂。由FTIR可知，MAH已接枝到PE-UHMW分子链上；当二甲苯、BPO和MAH用量分别为10，1.2，3份，反应温度为100℃，反应时间为4 h时，PE-UHMW-g-MAH的接枝率可达1.54%。

In order to connect the polar groups on the ultra-high molecular weight polyethylene(PE-UHMW) macromolecular chains,maleic anhydride (MAH) was grafted on PE-UHMW by solid phase grafting method using dimethylbenzene as the interfacial agent,benzoyl peroxide(BPO) as the initiator. The grafted product was characterized by FTIR,acid-base titration methods. The effects of the amount of interfacial agent,initiator,monomer,reaction temperature and time on the grafting degree were investigated in detail. The results show that when the amount of dimethylbenzene,BPO and MAH are 10,1.2 and 3 phr respectively,the grafting degree attain to 1.54%after carrying the reaction for 4 h at 100℃.
