A new preparation manner termed as "vine-twining Polymerization" was developed to produce amylose-polymer inclusion complexes. A first example of the polymerization method was achieved by an enzymatic polymerization of glucose 1-phosphate monomer catalyzed by phosphorylase in the presence of polyTHF as a guest polymer. The structure of the product was determined by the X-ray powder diffraction and NMR measurements to be the inclusion complex. The formation of the inclusion complexes by this polymerization method using polyTHFs with various molecular weights and end groups, as well as other polyethers as the guest polymers was also examined. Furthermore, polyesters were taken as guest polymers to form the corresponding inclusion complexes.Formation of inclusion complex of amylose with a strong hydrophobic polyester was examined in parallel polymerization system. The preparation of the inclusion complex was achieved in two enzyme-catalyzed polymerizations. The analytical data of the product indicated that the product contained the inclusion complex.An alginate-polymethacrylate hybrid material was prepared by radical polymerization of a cationic methacrylate monomer, i.e., 2-aminoethyl methacrylate hydrochloride in the presence of sodium alginate in water. The insoluble material was formed with progress of the polymerization. The structure of the product was confirmed by the IR spectrum and elemental analysis, as well as the acid hydrolysis experiment to be composed of alginate and polymethacrylate. The TG and DSC data of product were different from those of a mixture of sodium alginate with poly(2-aminoethyl methacrylate hydrochloride). Furthermore, the films of the hybrid materials could be formed by means of the polymerization of the methacrylate monomer in the presence of sodium alginate, followed by the evaporation of the solvent.

本文提出了一种新的制备直链淀粉-聚合物包合物的方法-葡萄缠绕聚合法。聚合方法的第一个实施例是在聚THF作为客体聚合物的存在下，通过磷酸化酶催化的葡萄糖1-磷酸单体的酶促聚合来实现的。产物经X射线粉末衍射和核磁共振测定，确定为包合物。通过这种聚合方法使用具有各种分子量和端基的polyTHFs，以及其他聚醚作为客体聚合物的包合物的形成也进行了检查。以聚酯为客体聚合物，在平行聚合体系中考察了直链淀粉与强疏水聚酯的包结作用。包合物的制备是在两个酶催化聚合。产物的分析数据表明产物中含有包合物。通过阳离子甲基丙烯酸酯单体的自由基聚合制备了海藻酸盐-聚甲基丙烯酸酯杂化材料，2-甲基丙烯酸氨基乙酯盐酸盐在海藻酸钠存在下在水中反应。随着聚合的进行，形成不溶性材料。通过红外光谱、元素分析和酸水解实验证实了产物的结构为海藻酸钠和聚甲基丙烯酸酯的混合物。产物的TG和DSC数据不同于海藻酸钠与聚甲基丙烯酸2-氨基乙酯盐酸盐的混合物。此外，杂化材料的膜可以通过在海藻酸钠存在下聚合甲基丙烯酸酯单体，然后蒸发溶剂来形成。
