Abstract
In the present work, predominantly syndiotactic polystyrene samples we re prepared with different catalysts and polymerization conditions and the obtained polymers were used for assignments of stereochemical str uctures of polystyrene. Assignment was carried out by comparison of C- 13 NMR spectra of polystyrenes with different syndiotacticity and base d on polymerization mechanism. Assignments were also compared with res ults in the previous work.
