Persistent Organic Chemicals In The Pacific Basin Countries: An Overview, Bommanna G. Loganathan
Persistent Organic Chemicals In The Pacific Basin Countries: An Overview, Bommanna G. Loganathan
Faculty & Staff Research and Creative Activity
The Pacific Basin is a unique geographical region representing tropical, temperate and polar zones. This region is home to 2/3 of world’s population and consists of rapidly growing economies (countries) and highly developed countries. The Pacific Basin countries have had a history of use of persistent organic chemicals (POCs) at varying proportions during the last five decades. Due to diverse climatic and socio-economic conditions, the environment and biota in different countries in this basin have varying degrees of environmental contamination and effects on wildlife and humans. In this chapter, the historical background of POCs including, discovery, production, use, regulations/restrictions imposed, …

Synthesis And Properties Of Bisimidazolium And Poly(Ethylene Glycol)-Containing Michael Addition Polyester Networks, Joshua Allan Dippie
Murray State Theses and Dissertations
Poly(ionic liquid)s (PILs) have been examined in recent years for applications in various technologies, including solid-state lithium ion batteries and gas separation membranes. In this work, a series of bisimidazolium-containing, Michael addition donors were synthesized and used to produce a series of covalently crosslinked PIL polyester networks containing bis(trifluoromethylsulfonyl)imide as the counteranion. Within the series, the length of alkyl spacer between the two imidazolium cations and the diacrylate to acetoacetate monomer ratio were varied in an attempt to correlate structural variations with the thermal, mechanical, and conductive properties of the PILs. Keeping the diacrylate to acetoacetate ratio constant, increasing the …
