Chemoenzymatic synthesis of amylose-grafted polyacetylenes by
means of phosphorylase-catalyzed enzymatic polymerization by
macromonomer method (a) and polymer reaction method (b).

Chemoenzymatic Synthesis of Amylose-
Grated Poly(Vinyl Alcohol)
Poly(vinyl alcohol) (PVA) film exhibits unique properties such as
formation of a complex with iodine, which has attracted much
