Semi-fluorinated core-shell latexes and model random polyampholytes
by Kaur, Baljinder, Ph.D., OKLAHOMA STATE UNIVERSITY, 2010, 164 pages; 3422276

Abstract:

Scope and Method of Study. Cationic polymer colloids in aqueous medium find applications in phase transfer catalysis. We have synthesized core shell latex particles with quaternary ammonium ion by emulsifier free shot growth emulsion polymerization. Model random polyampholytes are needed to test the modern theory of polyampholytes. We have synthesized random polyampholytes by living radical polymerization namely reversible-addition fragmentation chain transfer polymerization in order to understand dilute and semi-dilute solution properties of polyampholytes.

Findings and Conclusions. Hydrolysis of simulants of chemical warfare agents such as p-nitrophenyl hexanoate and Paraoxon was faster using cationic polymer dispersions than hydrolysis with coatings made from the aqueous dispersions. The aqueous solution properties of polyampholytes such as viscosity as function of pH and electrolyte concentration showed that the polyampholytes synthesized are charge imbalanced.
