A study of miscibility, morphology, crystallization and melting behavior of isotactic poly(propylene) in blends of poly(propylene) and poly(1-butene)
… thesis, the miscibility behavior of blends of polypropylene (PP) and poly(l-butene) (PB1) will be reexamined. The driving force for this study is the fact that contradictory conclusions on this subject exist in the literature. In this thesis, the glass transition behavior, morphology, …

Study of the miscibility, crystallization and morphology in poly(propylene) based blends and copolymers
This dissertation discusses the polymorphism, crystallization and melting behavior of propylene-ethylene random copolymers. It also discusses the results of studies of the miscibility and the competitive liquid-liquid demixing and crystallization processes in blends of poly(propylene) and …

Examination of Dynamic Processes in Living Ziegler-Natta Polymerization and New Polypropylene Architectures through Bimolecular Control
… highly active initiator for living alpha-olefin polymerization. Discrete cationic CPZA alkyl complexes of the general structure {Cp*ZrR[N(Et)C(Me)N(tBu)]}[B(Csub6Fsub5)sub4] were studied as model complexes for living polymers derived from this system. Detailed analysis of models in which R = nPr, …

Thermodynamic Interactions in Polydiene/Polyolefin Blends
Thermodynamic interactions in blends of polydienes and polyolefins were investigated using small angle neutron scattering (SANS). Model polydienes with controlled molecular weight, dispersity, and precise chemical structure were synthesized using anionic polymerization, and subsequently saturated …
