| 摘 要： | 在硝酸铈铵(CAN)以及硫酸亚铁/过氧化氢两种引发体系中，进行了丙烯酸乙酯(EA)、醋酸乙烯酯(VAc)与玉米淀粉的接枝共聚。用质子核磁共振研究了接枝支链的化学组成、用X衍射研究接枝共聚物结晶结构的变化、用扫描电镜研究了材料的微观结构、并研究了共聚物的亲水性。制备了接枝淀粉、聚乙烯醇的生物降解塑料，测定了材料的力学性能以及疏水性。

| Abstract: | Graft polymerization of ethyl acrylate (EA) and vin/1 acetate(VAc)onto corn starch were carried out in water with the initiator of cerous ammonium nitrate (CAN) or fenous sulfate/hydrogen peroxide(FAS/H2O2). Several techniques such as nuclear magnetic resonance ( NMR) , X-ray diffraction analysis ( XRD), differential thermograrimetry( DTG) , scanning electron microscope (SEM) were used to characterize the grafting copolymer . The hydrophilic property of the copolymer was investigated. At the same time, starch-PVA biodegradable material was gained by crosslinking ,and the mechanical properties and hydrophobic properties of this material were investigated. |
