Abstract

See full text

Compared to the prior art, this invention provides a functionalized highly syndiotactic polystyrene, comprising a repeating unit having a structure represented by formula (I), or comprising a repeating unit having a structure represented by formula (I) and a repeating unit having a structure represented by formula (II). It is indicated by the experimental results that the syndiotacticity selectivity of the highly syndiotactic polymer provided by this invention is no less than 90%, and the proportion of the repeating unit having a structure represented by formula (I) in the polymer may be arbitrarily adjusted and may be up to 100%. Meanwhile, the oxygen- or sulfur-containing groups in the polymer may increase the polarity of the highly syndiotactic polystyrene so as to increase the blendability of the highly syndiotactic polystyrene with other polymers.
