Synthesis of amylose-
block
-polystyrene by phosphorylase-
catalyzed polymerization.
The
synthesis
of
an
amphiphilic
methoxy
poly(ethylene
oxide) (MPEO)-
-amylose and its complexation with methyl
orange (MO) were investigated [11,12]. First, an MPEO-primer
was prepared by the condensation of maltopentanosylamine with
MPEO-
block
-nitrophenylcarbonate (Fig. 10.2). Then, the phosphorylase-
catalyzed polymerization of Glc-1-P from the primer was carried
out to give the MPEO-
p
-amylose. A sole amylose is insoluble in
chloroform, but the product was slightly soluble in chloroform. It
was confirmed that the complexation of the MPEO-
block
-amylose
with MO was significantly enhanced in the amylose domain of the
associate in chloroform.
