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 (Tg) of the unsaturated and saturated homopolymers. Results show that saturation reduces the density by 30% to 11%, Tg measurement reached 186°C for P2MVCH. Bulk chain statistics and the statistical segment length were determined.
