Summary
Diphenylzinc-water systems, Ph2Zn-H2O, were aged at various temperatures and for various lengths of time. These systems by themselves and those to which t-butyl chloride was added, Ph2Zn−H2O−ButCl, were used as initiator for styrene polymerizations. For Ph2Zn−H2O systems, both conversion and molecular weight of the polymers were much affected by ageing. Ph2Zn−H2O−ButCl systems, after ageing at various temperatures, did not improve their capability to induce styrene polymerization at-78°C in dichloromethane, confirming their ionic nature.
