摘要
淀粉与丙烯酸酯类单体的接枝共聚物有可能作为生物降解塑料,而被应用于农业、医药及食品等各个方面。因此寻求价廉、高效的引发剂,以用于引发淀粉与烯类单体的接枝共聚,已引起了人们的极大兴趣。 过渡金属离子与β二酮的配合物,如乙酰丙酮铁(Ⅲ)、乙酰丙酮锰(Ⅲ)、乙酰丙酮铜(Ⅱ)等是一类引起注目的新型引发剂,已在羊毛、蚕丝。
In this paper, the graft copolymerization of methyl methacrylate onto starch using acety-lacetonate copper (II) uomplex as initiator was studied. The percentage and efficiency of grafting were investigated by varping the concentrations of initiator, monomer and starch, various acids, trichloroacetic acid, and the reaction temperature. By varying these reaction parameters, the percentage and efficiency of grafting could be adjusted effectively.
