Abstract: In the presence of the initiator benzoyl peroxide (BPO), maleic anhydride (MAH) was grafted onto a kind of H-1 type fischer-tropsch wax by melt grafting process to improve the hardness and other indicators of Fischer-Tropsch wax. The experimental results show that, when the reaction lasted for 20 min at the reaction temperature of 140 ℃, the amount of maleic anhydride （MAH）was 5.0 g and the amount of initiator （BPO）was 4.0 g, the grafting rate reached 1.53% while the product's penetration degree was 1.6(0.1 mm). From the infrared spectroscopy (IR), we can see that MAH had been successfully grafted to the fischer-tropsch wax.

摘要： 以过氧化苯甲酰(BPO)为引发剂,采用熔融接枝的方法,将马来酸酐(MAH)接枝到H-1型费-托
蜡上,使费-托蜡的硬度等性质得到改善。实验结果表明,反应时间20min,反应温度140 ℃,马来酸酐质量5.0g,
引发剂质量4.0g时,接枝率达到1.53%,所得产品的针入度达到1.6(0.1mm)。经红外光谱分析,表明马来酸酐确
已接枝到费-托蜡上。
