摘　　要：对两性瓜尔胶接枝共聚物(LGG-g-PAM)在蔗渣漂白硫酸盐浆中的助留助滤性能进行了研究。实验表明:LGG-g-PAM7对浆料具有很好的助留和增强双重效果。LGG-g-PAM10显示出对沉淀碳酸钙(PCC)优越的助留效果。体系适宜pH范围是7～9,且该体系受高电导率的影响很小。细小纤维的首程留着率(FPR)随DDJ转速的增大而减小,但在转速小于1000r/min下助剂仍具有很好的助留效果。An investigation was carried out to the retention and drainage performance of amphoteric guar gum graft copolymer （LGG-g-PAM） in bleached bagasse sulfate pulp. The experiments indicate that LGG-g-PAM7 had a dual effect of favorable retention and strengthening. LGG-g-PAM10 had a superior retention effect on precipitated calcium carbonate（PCC）, The appropriate pH range for the system was 7-9, and high electrical conductivity had very little influence on the system. With the rotating speed of DDJ increasing, the first-pass retention （FPR） decreases, yet good retention effect was obtained when the rotating speed was less than 1000r/min.
