【摘要】 以过硫酸钾为引发剂，研究了丙烯酰胺与玉米淀粉接枝共聚的反应规律，实验结果表明：当［Ｋ＿２Ｓ＿２Ｏ＿８］＝－１００ｍｍｏｌ／Ｌ、［ＡＭ］＝０．４２２ｍｍｏｌ／Ｌ，在６０℃反应３ｈ，接枝率、接枝效率、单体转化率及产率都很高。更多还原

【Abstract】 The regularity of graft copolymerization of acrylamide onto corn starch initiated by potassi-um persulfate is investigated. The experimental results show that when[K₂S₂O₈]=100mmol/L.[AM]=0.422mmol/L and the reaction is carried out at 60C for 3h, the percent grafting, grafting ef-ficiency monomer conversion and yield are all high.更多还原
