Summary

Conductance stopped-flow analysis on the initial phase of cationic polymerizations of p-methoxystyrene and styrene revealed rapid changes in conductance (within 20–50 ms) that were related to the initiation process. Initiation rate constants were obtained for CF3SO3H, CH3COClO4, and BF3O (C2H5)2 initiators in 1,2-dichloroethane at 30°C. They agreed closely with those determined by stopped-flow spectroscopy, and decreased with increasing monomer concentration.
