S-g-PEMA接枝淀粉的合成

Synthesis of S-g-PEMA Graft Starch

研究了以玉米淀粉和甲基丙烯酸乙酯为原料，以ＫＭｎＯ４／Ｈ２Ｃ２Ｏ４引发体系合成Ｓ－ｇ－ＰＥＭＡ。ＳＥＭ和ＩＲ证明了产物的正确性，产物的接枝效率可达８０％以上。

This paper reports the graft copolymerization of ethyl methlacrylate onto corn starch using potassium permanganate /oxalic acid redox system as initiator.The products were confirmed by SEM and IR. The graft efficiency reached above 80%.
