## Abstract This paper reports the chemoenzymatic synthesis of an amylose‐grafted cellulose. A maltoheptaose was chemically introduced to the amine‐functionalized cellulose by reductive amination to produce the maltoheptaose‐grafted cellulose. Then, the phosphorylase‐catalyzed enzymatic polymerizat
## Abstract An amylose‐grafted chitosan has been synthesized by a chemoenzymatic method according to the following two reactions. First, maltoheptaose is introduced to chitosan by a reductive amination using sodium cyanotrihydroborate in a mixed solvent of 1.0 mol · L^−1^ aqueous acetic acid and me
## Abstract **Summary:** A macromonomer (**1**) consisting of a polystyrene chain and an acetylenic chain end ($\overline M \_{\rm n}$ = 2 500, $\overline M \_{\rm w} /\overline M \_{\rm n}$ = 1.20) was prepared by atom transfer radical polymerization. Macromonomer **1** was copolymerized with phen
