✦ Synopsis

The kinetics of the cationic polymerization of ethylene oxide by trityl salts have been studied in dichloromethane at 285 K and chlorobenzene at 298 K. As previously reported for the same polymerization in nitrobenzene [I] (J. Polym. Sci. Lett. Ed. 21,885, 1983L the internal order is unity, the paired and unpaired ions having the same reactivity. The lack of dependency of kp on g. is interpreted as due to solvation of the oxonium ions.
