摘　　要：对两性瓜尔胶接枝共聚物(LGG-g-PAM)在混合脱墨废纸浆中的助留性能进行了研究,探讨了聚合氯化铝加入方式、LGG-g-PAM用量、相对分子质量及阳离子电荷密度对细小纤维首程留着率的影响,并与阳离子瓜尔胶的助留性能进行了对比。This article dealed with the application of graft copolymer of amphoteric guar gum（LGG-g-PAM） as retention aid for recycled pulp,the factors such as the adding manner of PAC,the dosage of LGG-g-PAM, the molecule weight and the cationic charge density of LGG-g-PAM affecting the first-pass retention（FPR） were studied, and the cationic guar gum was used for comparison.
