聚丙烯酰胺的合成与研究

On the Conditions for the Reaction of Acrylicamine Polymerization

采用过硫酸钾—氮三丙酰胺引发体系 ,进行丙烯酰胺水溶液聚合。考察了溶液PH值 ,温度等工艺条件对产物分子量 ,转化率及聚合物溶解性能的影响。在PH=8,60℃时,氨水滴加7滴时,可得到分子量为62.00E4聚丙烯酰胺及转化率为98.94 %。

In this study with potassium persulfate nitroacryicamide mixed initiator,the aqueous solution of acrylic amide is carried out,and tthe influence of technological conditions (Such as PH value and temperature) on molecular weight transformation probability.etc.is also examined.
