| 摘 要： | 在K2S2O8/Na2SO3氧化-还原引发体系的引发下,通过甲基丙烯酰氧乙基三甲基氯化铵(DMMC)和烯丙基十烷基二甲基氯化铵(DDAMC)在羧甲基壳聚糖(CMCTS)分子链上的接枝共聚反应,制备了新型两性聚电解质壳聚糖衍生物CMCTS-g-(PDMMC-co-PDDAMC)。对产物的两性聚电解质性能进行了初步的探索性研究,发现CMCTS-g-(PDMMC-co-PDDAMC)在pH=1和pH=11处各出现一个黏度较大值,在pH=5附近达到等电点,黏度最小。在等电点处溶液黏度η和特性粘数η]随离子强度的增大而增大,在pH=1和pH=11处溶液黏度随离子强度的增大而减小。研究了阳离子种类对CMCTS-g-(PDMMC-co-PDDAMC)溶液黏度的影响。

| Abstract: | The novel polyampholyte derivate of chitosan,CMCTS-g-(PDMMC-co-PDDAMC),was prepared through the graft copolymerization of dimethylaminoethyl methacrylate methyl chloride(DMMC) and decyl dimethyl allyl ammonium chloride (DDAMC) on the chain of carboxymethyl chitosan,intiated by K2S2O8/Na2SO3 redox initiation system. The polyampholyte properties of CMCTS-g-(PDMMC-co-PDDAMC) was studied primarily in this paper. The viscosity reached the maximum at pH=1 and pH=11 respectively. The viscosity was reduced to minim... |
