Outlines of Chemoenzymatic Synthesis of
Amylose-Grafted Synthetic Polymers by
Utilizing Phosphorylase Catalysis
As the natural polysaccharides such as amylose are recycled carbon
resources and considered to be eco-friendly substances [1,2], it is
expected that the use of the polysaccharides as one component of
hybrid polymers will lead to the production of environmentally
benign materials.
Graft copolymer is one of the hybrid polymers widely applied
in the industrial fields [3], and has the structure of polymer main
chain as a backbone covalently linked to graft chains as branches.
However, graft copolymers containing polysaccharides have only
been obtained in limited cases. As examples of such materials, a
type of graft copolymers composed of polysaccharide main chains
and synthetic polymer graft chains is common [4,5]. However,
little has been reported regarding preparation of graft copolymers
containing polysaccharide graft chains. Because the solubility of
polysaccharides is generally poor in any organic solvents, direct
