摘　　要：以苯乙烯(St)和马来酸酐(MA)为单体、过氧化苯甲酰为引发剂和丙酮为溶剂,采用自由基无规共聚法合成了St-MA共聚物(SMA);然后以改性松香作为SMA的接枝改性剂,制成的SMA-松香接枝共聚物(SMA-g-松香)乳液作为纸张施胶剂。结果表明:经SMA-g-松香施胶液处理过的纸张,其施胶度、平滑度和耐破度均比SMA施胶纸提高了33.3%、22.2%和20.7%。With styrene（St） and maleic anhydride（MA） as comonomers,benzoyl peroxide as initiator and acetone as solvent,so a St-MA copolymer（SMA） was prepared by random copolymerization with free radical.Then a SMA grafted by modified rosin（namely SMA-g-rosin）,which was used as sizing agent for paper surface,was prepared.The results showed that the sizing degree,smoothness and bursting strength of the paper treated by SMA-g-rosin sizing were more 33.3%、22.2% and 20.7% than those of the paper treated by SMA sizing.
