丙烯酸与土豆淀粉接枝共聚反应规律的研究

Study on Regularities of Graft Copolymerization of Acrylic Acid onto Potato Starch

本工作用硝酸铈铵作引发剂,研究了丙烯酸与土豆淀粉接枝共聚的反应规律.实验结果表明,丙烯酸浓度为0.769mol/L,引发剂浓度为2.632mmol/L,淀粉预处理温度为85℃,反应温度为40℃,反应时间2h 为最佳反应条件.

In this paper,we here reported the regularities of graft copolymerizationof acrylic acid(AA)onto potato starch using ceric ammonium nitrate asinitiator.Results showed that the optimums are the concentrations ofAA and initiator is 0.769mol/L and 2.632mol/L respectively,thetemperatures of starch pretreatment and reaction are 85 ℃ and 40℃respectively,the time of reaction is 2 hr.
