| 摘 要： | 为提高石蜡的极性,在引发剂过氧化苯甲酰作用下,采用石蜡与马来酸酐进行接枝反应,考察了反应温度、引发剂和马来酸酐用量对产物接枝率的影响。适宜的反应条件为:反应温度为80℃,引发剂和马来酸酐的用量分别为石蜡的3%和8%,并且马来酸酐与引发剂一起分8次加料,每10 min加1次,产物的接枝率为0.909%。

| Abstract: | In order to improve the wax's polarity,benzoyl peroxide(BPO)was used as the initiator of polymerization to graft maleic anhydride(MAH)onto wax.The influencing factors such as the tem- perature,the dosage of initiator and maleic anhydride were studied.The optimal reaction conditions were found as follows:reaction temperature 80℃,3% BPO,8% MAH,MAH and BPO being added into the system together by eight times in ten minutes interval.A high grafting ratio of 0.909% was obtained.The IR spectra showed that the product had the observable vibration of carbonyl,indicating that maleic anhydride was grafted onto wax,and the wax's polarity was improved. |
