摘　　要：首先以魔芋葡甘聚糖为原料,制备羧甲基化魔芋葡甘聚糖(CKGM),然后在水介质中,以过硫酸钾为引发剂,引发羧甲基魔芋葡甘聚糖(CKGM)与甲基丙烯酰氧乙基三甲基氯化铵(DMC)接枝共聚,制备系列含阳离子季铵盐基团的CKGM-gPDMC接枝共聚物,系统考察了反应条件对接枝共聚物接枝率(GR)和取代度(DS)的影响,与此同时,用FTIR对接枝共聚物结构进行了表征。Konjak glucomannan was modified by carboxymethylation. Using potassium persulfate as initiator,a series of cationic polymers was prepared by grafting methacryloxyethyltrimethyl ammonium chloride（ DMC） onto carboxymethyl konjac glucomannan in aqueous solution. The influences of reaction condition on the percentage of grafting（ GR） and degree of substitution（ DS） were investigated. Meanwhile,structures of the graft copolymers were characterized by FTIR.
