Edaravone, an electron spin trapper with radical scavenging activity, has been shown to be effective in reducing infarct volume in humans following ischemic stroke. However, concerns of edaravone-induced renal toxicity have limited its clinical adoption. Previous work has demonstrated that edaravone...

This thesis describes the synthetic strategies for the incorporation of a number of metal species into a series of polynorbornenes, as well as their characterization and thermal analysis. This was accomplished through the synthesis of new monometallic norbornene compounds containing chromium and iro...

Radical polymerization of organoiron (alkynyl methacrylate)s afforded a series of organoiron poly(alkynyl methacrylate)s with the ability to coordinate dicobalt hexacarbonyl. The polymers were post-modified with dicobalt hexacarbonyl moieties through reaction with dicobaltoctacarbonyl. Gel permeatio...

Metal-containing conducting polymers are a new and interesting class of materials that combine some of the redox properties of conducting polymers and some of those of the metal ions. In metal-containing conjugated polymers, there are several possible arrangements of metal group relative to the back...

The Vyazovkin model-free method were applied to study non-isothermal degrdn. of an aryl and hetaryl azo dye-contg. polynorbornene using a differential scanning calorimetric (DSC) technique. The samples were heated in nitrogen, with heating rates in the range 5-50 K min-1. The isoconversional method ...
