摘要/Abstract

摘要： 用十六烷基三甲基溴化按(CTAB)作标准物。溴酚兰(BPB)作分相指示剂，三氯甲烷作分相
溶剂，以721分光光度计测定(CTAB)的光密度，得到正氯离于含黄同光密度之问的关系曲线。以此曲线作为标准曲线，在同等条件下侧定含正氯离子侧基阳离子聚合物的光密度，对照标准曲线求含正氯离子侧基阳离子聚合物的阳离子度。

关键词: 溴酚兰, 阳离于一聚合物, 阳离子度, 光密度

Abstract: The relative curve between the content of nitronium ions and the light density is mea-sured by means of model 721 chromophotomer, with cetyltrimethyl ammonium bromide as a standard sample，bromophenolblue as an indicator and trichloromethame as a solvent. Under the same condition，the cationic degree of cationic polymer is obtained by comparing the standard curve with those of light density of cationic polymer containing cationic nitrogenium pendent groups.

Key words: Bromophenolblue, Cationic degree, Cationic polymer, Optical density
