Therefore, the preparation of hydrogels through the formation of
an inclusion complex of amylose in the vine-twining polymerization
was investigated [13]. This was achieved by the phosphorylase-
catalyzed polymerization of Glc-1-P from Glc
in the presence of a
water-soluble copolymer having the hydrophobic PVL graft chains;
