Three high-molecular-weight pyridine amines, 5-(4-pyridyl)nonane, 2-hexylpyridine, and diphenyl-2-pyridylmethane, have been studied as components of solvent extraction systems. Results are presented to show the dependence of the uranium extraction coefficient (Dao = [Uorg]/[Uaq]) on equilibrium...
Styrene emulsion polymerization using an alkyl-9-BBN, synthesized by reacting 9-BBN(9-borabicyclo-[3.3.1]-nonane) and styrene, in an aqueous sodium dodecyl sulfate(SDS) solution was studied. Ultra-high-molecular-weight(> 1.0 × 10~7) polystyrene was synthesized using a radical initiator formed...
