摘　　要： 以丙烯酰胺(AM)和丙烯酰氧乙基三甲基氯化铵为共聚单体,采用分散聚合法在无机盐水溶液中制备了性能稳定的阳离子聚丙烯酰胺(CPAM)乳液。对所得产物进行了红外光谱和粒径分析。动态滤水实验表明自制CPAM对漂白苇浆具有良好的助留助滤作用。 Copolymer of aerylamide （AM） and acryloyloxyethyl trimethyl ammonium chloride was prepared by dispersion polymerization in a salt solution. The copolymer molecular structure was identified by the analysis of IR. The size of the dispersed particles and their distribution were measured. The product was applied in bleached reed pulp as retention and drainage aids. The results showed that the copolymer could remarkably improve retention and drainage of the pulp.
