摘　　要：造纸白水循环系统中溶解和胶体物质(DCS)的富集会导致纸机运行异常,纸张性能下降。本研究以添加RAFT试剂的方式制备了三种不同粒径的聚甲基丙烯酰氧乙基三甲基氯化铵(Poly-MAC)表面接枝改性的阳离子化聚苯乙烯树脂微球用于处理造纸白水中DCS物质。结果显示,当粒径为411μm的改性树脂微球添加量为5.0g/L时,处理60℃的造纸白水1h,白水中阳离子需求量下降59.2%,浊度下降18.9%,总DCS下降14.7%。用红外光谱、核磁共振碳谱等对改性微球的结构进行了分析和表征。The enrichment of dissolved and colloidal substances （DCS） in the papermaking white water circulation system will result in the abnormal operation of paper machine and decrease the performance of paper. In this study, we prepared three different particle size of cationic polystyrene microspheres modified by poly （ methacryloyloxyethyl trimethyl） ammonium chloride （Poly- MAC ） in adding RAFT reagent conditions for treatment of DCS in papermaking white water. The results showed that, when the adding quantity of modified resin microspheres （particle size is 411 μ m） was 5.0 g/L, the treatment temperature and time was 60℃ and 1 hour, the white water cationic demand fell 59.2%, turbidity decreased 18.9%, total distributed control system （DCS） fell by 14.7%. The structures of the modified microspheres were characterized by FT - IR and 13C - NMR.
