Characteristics and Mechanism of Styrene Cationic Polymerization in Aqueous Media Initiated by Cumyl Alcohol/B(C₆F₅)₃

Styrene cationic polymerizations initiated by cumyl alcohol (CumOH)/B(C 6 F 5 ) 3 are systematically studied in aqueous suspension and emulsion. Theoretical calculations and experimental research suggest that CumOH/B(C 6 F 5 ) 3 has higher initiating activity than H 2 O/B(C 6 F 5 ) 3 . During emulsion polymerization of styrene, molecular weight and polymerization rate decrease with the addition of surfactants. These polymerization processes...
