摘要: 用过硫酸铵和四甲基乙二胺氧化还原引发体系合成了羧甲基纤维素接枝甲基丙烯酸二甲胺基乙酯两性共聚物(CGD),研究了反应温度、pH、原料羧甲基取代度、引发剂用量、反应物料配比和外加盐对接枝共聚的影响,并用红外光谱对接枝共聚物结构进行了鉴定Abstract: The graft copolymer of novel amphoteric cellulose CGD was synthesized by the graft copolymerization of sodium carboxymethyllcellulose (CMC) with dimethylaminoethyl methacrylate( DMAEMA) using ammonium persulfate ( APS ) and N,N ,N,N-tetramethyl ethylene
