【摘要】 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3h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%。更多还原

【Abstract】 With using polyamide epihalohydrin resin as reaction agent and ammonium persulfate as initiator,cationic crosslinking PAE/CPAM interpenetrating polymer network(IPN)was prepared by the free radical polymerization method of glycidyl methacrylate(GMA),acrylamide(AM),methacryloyloxyethyl trimethyl ammonium 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 is2.42%,the reaction temperature 70 ℃,reationing 3h.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%.更多还原
