摘　　要：以过氧化苯甲酰(BPO)为引发剂,采用水相悬浮法制备苯乙烯(St)、马来酸酐(MAH)双单体接枝聚丙烯共聚物(PP-g-St/MAH),结果表明,较优的接枝反应条件为BPO/St/MAH/水/PP投料质量比0.04/1.00/1.00/25.00/10.00,60℃溶胀2 h后90℃反应5 h。在此条件下,产物接枝率为8.97%,接枝效率为44.85%。With benzoyl peroxide （BPO） as initiator, styrene（St） and maleic anhydride（MAH） as grafting monomers, the graft polymer PP-g-St/MAH was prepared by means of water suspension method. The results show that the optimal conditions for grafting reactions are that the mass ratio of BPO/St/MAH/H2O/PP is 0. 04/1.00/1.00/25.00/10.00, and PP is grafted at 90 ℃ for 5 h after swelling at 60 ℃ for 2 h. Under these conditions the maximum grafting ratio of PP-g-St/ MAH is 8. 97M and grafting efficiency of PP-g-St/MAH is 44.85 %.
