摘要
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 through the aerobic oxidation of this alkyl-9-BBN in a high yield(〉 80%). The kinetics of this emulsion polymerization of styrene with the alkyl-9-BBN was investigated. We confirmed that in the initial stage of the polymerization, the initial reaction rate followed first-order kinetics. The activation energy for this emulsion polymerization of styrene was approximately 56.2 kJ/mol.
