Notes:
Employing a reproducible system for the emulsion polymerization of styrene it has been demonstrated that agitation (stirring or shaking) affects both the rate of polymerization and maximum average molecular weight of the polymer formed. Increasing the agitation increases the inhibition, decreases the polymerization rate, and lowers the average molecular weight of the polymer formed. Agitation affects both a peroxide and a persulfate catalyzed polymerization in a similar manner. Agitation effects have been observed in the presence of a redox system and in the presence of a chain modifier. Oxygen has been demonstrated to stop as well as inhibit the initiation of an emulsion polymerization.
