Abstract

Six nearly monodisperse substituted poly(styrene) homopolymers, poly(styrene) (PS), poly(2 methylstyrene) (P2MS), poly(3-methylstyrene) (P3MS), poly(4-methylstyrene) (P4MS), poly(tertiary - butylstyrene) (PtBS) and a poly(α-methylstyrene) (PαMS) were anionically polymerized and subsequently saturated using heterogeneous hydrogenation techniques. The materials except for PαMS were saturated to >99% conversion with no chain degradation. The density gradient technique and differential scanning calorimetry were utilized to characterize the densities and glass transition temperature (T_g) of the unsaturated and saturated homopolymers. Results show that saturation reduces the density by 30% to 11%, T_g measurement reached 186°C for P2MVCH. Bulk chain statistics and the statistical segment length were determined.
