Polyacrylonitrile polymers produced in the presence of molar equivalen
ts of P-cyclodextrin (BCD) showed variation in stereoregularity. Thus,
an increase in the acrylonitrile:BCD ratio showed an increase in isot
acticity in the polymers formed. Inclusion complexation of acrylonitri
le by BCD was detected by both H-1-NMR spectroscopy and UV-Vis spectro
scopy, which gave a binding constant value of 7242 +/- 360 M(-1) for t
he 1:1 complex.
