Influence of a diene impurity on the molecular structure of phosphate-containing polymers with medical applications. Grondahl, Lisbeth, Suzuki, Shuko and Wentrup-Byrne, Edeline () Influence of a diene impurity on the molecular structure of phosphate-containing polymers with medical applications. Each case study will examine: 1) the background of the community or communities using the waste to energy plant; 2) the reasons that WTE selected as a waste disposal option; and 3) the impact of WTE on the community. 1 As defined by the EPA, MSW consists of everyday items such as product packaging, grass clippings, furniture. Described herein are three projects centered on the synthesis of conducting polymer derivatives for various applications. The first is the novel synthesis of 9,9-dioctylfluorene-co-benzothiadiazole [F8BT] oligomers through solid phase synthesis for the study of the thermodynamics and kinetics of electron transfer in the polymer.

Inorganic polymers, polysiloxanes contain alternate silicon and oxygen atoms as their backbone. The silicon atom has two side groups while the oxygen atom carries none.
In this regard they are similar to polyphosphazenes [,]. The pioneering work on polysiloxanes dates back to –, to the studies of Friedel, Crafts, and Ladenburg.
