Figure 5.3
Chemoenzymatic synthesis of amylose-grafted polystyrene by
means of phosphorylase-catalyzed enzymatic polymerization.
In addition, the phosphorylase-catalyzed enzymatic
polymerization was also performed using poly[styrene-
-(4-
vinylbenzyl maltohexaoside)] as the primer-grafted polystyrene,
which was prepared by a two-step 2,2,6,6-tetramethylpiperidine-
1-oxyl (TEMPO)-mediated living radical polymerization of styrene
and 4-vinylbenzyl maltohexaoside, to afford poly[styrene-

Researches concerning conjugated polymers have attracted much
attention in terms of the various practical applications of their
