以聚酰胺多胺环氧氯丙烷(PAE)溶液为反应介质,过硫酸铵为引发剂,丙烯酰胺(AM)、甲基丙烯酸缩水甘油酯(GMA)、甲基丙烯酰氧乙基三甲基氯化铵(DMC)为单体,采用自由基聚合的方法制备出阳离子型CPAM/PAE顺序互穿网络聚合物(IPN).红外光谱图表明自由基单体聚合成功；SEM扫描电镜图显示,不同比例复配的PAE和CPAM混合物呈空间网络交联结构.研究表明,当ω(PAE)＝60．56％,ω(AM)＝2．42％,ω(DMC)＝2．42％,聚合温度为70℃,时间为3 h的条件下合成固含量为30％的阳离子互穿网络聚合物应用于纸张中,IPN 添加量为1％,能提高纸张干抗张指数17．44％,湿抗张指数26．78％,撕裂指数39．84％,耐折度71．94％,耐破指数41．49％.
With using polyamide epihalohydrin resin as reaction agent and ammonium persulfate as initiator,cat-ionic crosslinking PAE/CPAM interpenetrating polymer network (IPN)was prepared by the free radical poly-merization method of glycidyl methacrylate(GMA),acrylamide (AM),methacryloyloxyethyl trimethyl ammo-nium chloride (DMC)as monomers.The free radical polymerization could be epoxided by means of Fourier transform infrared spectroscopy(FT-IR);The scanning electron microscopy(SEM)photographs show that the mixtures with different mass ratios of PAE and CPAM present a spatial network structure.What is more,the mass fraction of PAE resin is 60.56%,the addition quantity of AM is 2.42%,the addition quantity of DMC is 2.42%,the reaction temperature 70 ℃,reationing 3 h.Cationic interpenetrating polymer network polymers product of 30% solid content is applied in the paper,when the addition quantity of IPN is 1%,The dry and wet tensile index increased by 17.44% and 26.78%,folding resistance degree by 39.84%,tearing index by 71.97%, the burst index by 41.49%.
