Synthesis and Characterization of a Novel Acrylonitrile-based Copolymer Containing Sugar Moieties

利用无保护的糖内酯与甲基丙烯酸-2-氨乙基酯盐酸盐反应高效简便合成了一种新颖的直链糖,并用水相沉淀聚合的方法将其与丙烯腈进行了共聚合。考察了单体配比、聚合时间、引发剂浓度和总单体浓度对聚合行为的影响,红外、核磁用来表征聚合物,证明水相沉淀聚合是一种有效的聚合方式。

In this paper, the synthesis of a novel copolymer containing linear sugar moieties by the copolymerization of D-glueonamidoethyl methaerylate （GAMA） with acryontrile （AN） was reported. The effects of monomer feed ratio, reaction time, initiator concentration, and total monomer concentration on the eopolymerization were studied. FT-IR and 1H NMR spectroscopes were used to characterized the eopolymers. It was found that the eopolymerization under as high as 20% monomer feed ratio can be fulfilled by the water-phase precipitation eopolymerization with （NH4 ）2S2O8-NaHSO3 as initiator.
