Polybenzimidazole synthesis from compounds with sulfonate ester linkages

Creator:: Seckin, Turgay
Abstract:: This investigation of polybenzimidazole synthesis involved the two-stage low temperature solution polymerization of dialdehydes, One-step polycondensation of dialdehydes, two-stage melt polycondensation of diesters, and one-step solution polycondensation of diesters with 3,3'-diaminobenzidine. Dialdehyde or diester monomers were prepared which contained aromatic units which were hooked together with sulfonate linkages. Polymerization of...

Human exposure to polycyclic aromatic hydrocarbons : global cancer risk and metabolism

Creator:: Motorykin, Oleksii
Abstract:: In recent decades, there has been increased attention on human exposure to, and subsequently toxicity of, Polycyclic Aromatic Hydrocarbons (PAHs). PAHs are widespread organic pollutants and some have been shown to be toxic, carcinogenic and mutagenic. This research was focused on understanding the link between global PAH emissions and lung...

Total Synthesis of Tryptamine Alkaloids from the Arundo and Leuconotis Genera

Creator:: Ferreira, Andrew
Abstract:: The first part of this manuscript is about the total synthesis of the Arundo donax bis(indole) natural products. The A. donax alkaloids were prepared using the first example of an ynindole Diels–Alder reaction. Each were then separated, isolated, and determined to have stable enantiomeric conformations at room temperature (Chen, J.;...

Design, development and optimization of a fluorometric reaction-rate instrument and method of analysis for metal ions

Creator:: Wilson, Robert Loren
Abstract:: The design, construction and operation of a fluorometric reaction rate instrument is described. The instrument is designed for simple operation with maximum versatility. Advantages and modes of operation of the system are discussed in detail. The instrument is used for the kinetics-based determination of trace levels of Ag and Al....

Synthesis of polybenzimidazoles from monomers containing flexible linkages

Creator:: Azmus, Dora J. Taylor
Abstract:: Polybenzimidazoles were synthesized from 3, 3', 4, 4'-tetraminobiphenyl (diaminobenzidine, or DAB) with orthoesters, carboxylic acid derivatives (an ester and an acid) and with m-benzenedialdehyde. The products were of low molecular weight, as evidenced by low inherent viscosity, except in the case of the dialdehyde plus DAB. The product of that...
