摘　　要：以苯乙烯、甲基丙烯酸缩水甘油酯、异戊二烯为原料合成具有环氧基团、碳碳双键等活性基团的不饱和造纸湿强剂,利用傅里叶-拉曼光谱分析仪分析产物的结构,并探讨添加不同助留剂对纸浆Zeta电位、纸页物理性能的影响。实验结果表明:阳离子瓜尔胶作为助留剂时,纸页的湿强性能提升较大,当添加量为0.2%时,纸页的湿强指数达到7.43N·m·g-1,湿强保留率达到了20.3%。Unsaturated wet-strength agent was synthesized with styrene（St）,glycidyl methacrylate（GMA） and isoprene,which contains some reactive groups such as carbon-carbon double bonds and epoxy groups.Fourier-Raman spectrometer was used to analyze the structure of polymer.Through a large number of experiments,it is showed that cationic guar gum（CGG） as a retention agent has a better wet strength performance.When the addition is 0.2%,wet strength index of handsheets has reached 7.43N·m·g-1,and wet strength retention rate has reached 20.3%.
