Compared with the prior art, the present invention provides a functional high-syndiotactic polystyrene having repeat units as represented by structures of formula (I) or formula (I) and (II). The experimental results show that the syndiotactic selectivity of the high-syndiotactic polymer provided by present invention is not less than 90%, and the proportion of the repeat units as represented by structure of formula (I) in the polymer can be optionally adjusted and be up to 100%. Meanwhile, the polymer containing oxygen or sulfur group can increase the polarity of the high-syndiotactic polystyrene, thereby increasing the blend properties of the high-syndiotactic polystyrene and other polymers. |
