摘　　要：采用过硫酸钾引发甲基丙烯酸缩水甘油酯(GMA)与红麻纤维(KF)接枝共聚(产物为KF-g-GMA),考察了反应条件对接枝率的影响,探讨了不同体系下复合材料的力学性能。结果表明,在GMA与KF质量比为2:1,反应温度90℃时,接枝率较高,丙烯腈/丁二烯/苯乙烯共聚物(ABS/KF-g-GMA)复合材料的力学性能和吸水性能得到明显改善。With potassium persulfate as an initiator, kenaf fiber（KF） was grafted with glycidyl methacryiate（GMA）, the influences of reaction condition on grafting ratio were investigated. The mechanical properties show that the grafting ratio of KF-g-GMA of composites were discussed. The results copolymer increases when the mass ratio of GMA to KF is 2 ： 1 at 90 ℃. The mechanical properties and water-absorptiion performance of ABS/KF-g-GMA composites are improved significantly.
