【摘要】 研究了淀粉和丙烯酰胺接枝共聚物的胺甲基化反应合成阳离子高分子化合物。试验各种反应条件对胺甲基化反应的影响。通过红外光谱分析产物的结构,证实淀粉和丙烯酰胺接枝共聚后再进行胺甲基化,在一定条件下可以得到胺甲基化率更高的阳离子高分子化合物。更多还原

【Abstract】 Aminomethylation reaction of starch-polyacrylamide graft copolymer was investigated. The effect of temperature, reagent ratio and pH of the medium was discussed. The structural determination of the product by FTIR gave the same conclusion as chemical analysis. It has been proved that starch-polyacrylamide graft copolymer can give a higher aminomethylation yield than polyacrylamide.更多还原
