摘　　要：采用溶液聚合制备了新型阳离子共聚物——聚丙烯酰胺基-丙烯酰氧乙基三甲基氯化铵(P(AM-DAC)),采用滴定法测定了其阳离子共聚物的阳离子度。分别采用Fineman-Ross法、Kelen-Tudos法和Yezrielev-Brokhina-Roskin法计算出单体竞聚率。结果表明,KT法和YBR法计算较为准确,丙烯酰氧乙基三甲基氯化铵和丙烯酰胺的竞聚率分别为rDAC=0.3835,rAM=2.2864。The cationic copolymer was prepared from monomer acylamide（AM） and 2-（acyloyloxy）ethyl trimethylammonium chloride（DAC） by solution polymerization.The cationic degree of the copolymer was determined by the titration,the reactivity ratios of the cationic copolymer were obtained by the Fineman-Ross method,Kelen-Tudos method and Yezrielev-Brokhina-Roskin method,respectively.The results show that the values of the reactivity ratios determined by K-T method and YBR method are more accurate.The reactivity ratios of AM and DAC are ^-rDAC=0.383 5,^-rAM=2.286 4 calculated by K-T method and YBR method.
