| 摘 要： | 以丙烯酰胺(AM)、甲基丙烯酰氧乙基三甲基氯化铵(DMC)及二甲基二烯丙基氯化铵(DMDAAC)为原料,水溶性偶氮化合物为引发剂,采用水溶液聚合法合成了三元共聚阳离子型聚丙烯酰胺絮凝剂。考察了阳离子单体配比、单体质量分数、反应时间、引发剂用量及反应温度对聚合物相对分子质量的影响。结果表明,该三元共聚物的相对分子质量可达5.0×106,且水溶性好;对煤泥水具有良好的絮凝效果。

| Abstract: | The ternary cationic flocculant P(AM-DMC-DMDAAC) was synthesized by aqueous solution polymerization with raw materials of acrylamide(AM),methacryloyloxyethyl trimethyl ammonium chloride(DMC) and dimethyl diallyl ammonium chloride(DMDAAC) and with water-soluble azocompound as initiator.Effects of cationic monomer ratio,monomer mass fraction,reaction time,amount of initiator and reaction temperature on the molecular weight of the products were investigated.The results indicate that the molecular weight of the copolymer can reach 5.0×106,and the terpolymer demonstrates excellent water-dissolubility.Meanwhile,the terpolymer shows high capacity for flocculating performance in slurry. |
