Formation of amylose-polymer inclusion complexes by means of enzymatic polymerization of glucose 1-phosphate monomer in the presence of various guest synthetic polymers

摘要

Amylose, a natural linear polysaccharide linked through (1→4)-α-glycosidic linkages, is a well-known host molecule forming helical inclusion complexes with various low molecular weight organic compounds by hydrophobic interaction between guest molecules and the cavity of amylose. Although amylose has formed inclusion complexes with a few polymeric guest, i.e., polymer-polymer inclusion complexes, scope and limitation for formation of polymer-polymer inclusion complexes using amylose have not been well surveyed. The main difficulty of incorporating polymeric materials into the helical cavity of amylose is that the driving force for the binding is caused by only hydrophobic interaction. Amylose, therefore, does not have sufficient ability to include the long chains of the polymeric guests into its cavity.
