Stereochemical assignment of 13C NMR spectra of predominantly syndiotactic polystyrene

Abstract

In the present work, predominantly syndiotactic polystyrene samples were prepared with different catalysts and polymerization conditions and the obtained polymers were used for assignments of stereochemical structures of polystyrene. Assignment was carried out by comparison of 13C NMR spectra of polystyrenes with different syndiotacticity and based on polymerization mechanism. Assignments were also compared with results in the previous work.
