Observation of main chain chirality in isotactic polystyrene
… this thesis was to study main chain chirality in isotactic polystyrene. A stereoselective titanium based catalyst was developed and compared with other group IV metal catalysts in terms of activity and selectivity in olefin polymerization.

A study of the crystallization kinetics of isotactic polystyrene
… rate data for a molecular weight series of isotactic polystyrene are analyzed in context of the Lauritzen-Hoffman kinetic theory of polymer crystallization. The primary objectives of the study are to critically test the Lauritzen-Hoffinan theory under conditions not rigorously investigated …

Evaluating the Time-Dependent Melting Behavior of Semicrystalline Polymers Through Strobl's 3-Phase Model
… and subsequent melting behavior of isotactic polystyrene are explored in the context of Stroblâ "s 3-Phase model using differential scanning calorimetry (DSC), small angle X-ray scattering (SAXS), and wide angle X-ray diffraction. DSC experiments confirm the existence of a …
