摘要
以淀粉 (St)、二甲基二烯丙基氯化铵 (DMDAAC)、丙烯酰胺 (AM)为原料 ,采用 Fe2 + - H2 O2 氧化还原引发体系 ,合成了接枝共聚物。研究了单体浓度和单体配比等因素对接枝体系的接枝率、单体转化率、阳离子度等因素的影响 ,得到了 Fe2 + - H2 O2 -抗坏血酸引发淀粉接枝共聚反应的基本规律。采用红外光谱和核磁共振谱对接枝共聚物进行了结构分析。
Using Fe 2+ H 2O 2 initiation system, a graft copolymer was synthesized by copolymerization of starch with dimethyl diallyl ammonium chloride (DMDAAC) and acryamide(AM). Effects of various factors such as monomer/starch ratio and composition of monomer mixtures etc., on the percentage of grafting, the grafting efficiency, the monomer conversion and cationic degree etc. were studied. The mechanism of grafting polymerization on starch in initiation system was also discussed. And the graft copolymers were characterized and analyzed by IR and 1H NMR.
