Abstract
Diphenylzinc-water-organic monochloride systems, Ph(2)Zn-H2O-RCl with n-, sec- and tert-butyl chloride (t-BuCl) and benzyl chloride (BzCl), were used to induce styrene polymerization. Improvement in polymer con version is in concordance with the enthalpy of dissociation of the org anic chloride employed. Polymerization results suggest that systems wi th t-BuCl and BzCl proceed by coordinate cationic propagation. Obtaine d polystyrene was atactic with up to 75% syndiotactic triads detected by H-1-NMR spectroscopy.
