Abstract
Polyacrylonitrile (PAN) polymers were prepared by inclusion
polymerization of the monomer using various molar equivalents
of b-cyclodextrin (b-CD). Stereoregular (isotactic, atactic and
syndiotactic) distributions of the prepared PAN polymers were
determined from terminal model Bernoullian statistics using 13CNMR
data. With an increase in acrylonitrile (AN): b-CD ratios,
the proportion of isotactic polymers increased. Also, Tg increased
along with degradation temperature at higher AN: b-CD ratios.
However, molecular weight of the polymers prepared was lower
at an AN: b-CD ratio of 10:1, but was found to be larger than the
control at an AN: b-CD ratio of 20:1.
