摘　　要：以丙烯酰胺(AM)、衣康酸(IA)、甲基丙烯酰氧乙基三甲基氯化铵(DMC)及N,N-甲叉双丙烯酰胺(MBA)为单体进行两性聚丙烯酰胺(Am PAM)的合成,将合成的Am PAM加入混合废纸浆中进行抄纸。通过纸张各项强度指数的测量,确定其最佳合成工艺条件。结果表明,添加DMC-IA-AM型两性聚丙烯酰胺的纸张比原纸的各项强度指数有明显升高;在反应温度为70℃、时间为6 h、p H值为7、引发剂用量为0.6%(基于单体质量)、n(阴离子)∶n(阳离子)=0.3∶0.3的条件下合成的两性聚丙烯酰胺(Am PAM)对纸张的增强效果最为明显。We used acrylamide,itaconic acid,methyl acryloyl oxygen ethyl trimethyl ammonium chloride and N,N-methylene double acrylamide as monomer to synthesize amphoteric polyacrylamide（ Am PAM）. We added the synthetic Am PAM into waste pulp and measured paper strength index to determine the optimum synthesis conditions. The intensity index of paper mixed with DMC- IA- AM amphoteric polyacrylamide was increased significantly. When the synthesis conditions were under 70 ℃,6 h,p H of 7,initiator of 0. 6%,and the anionic and cationic monomer ratio of 0. 3∶ 0. 3,the paper performance and the effect on dry strength were the best.
