POLYMERIZATION OF STYRENE WITH DIPHENYLZINC-BUTANONE SYSTEMS

In the present work we report the results of the Polymerization of sty rene using diphenylzinc-butanone, Ph2Zn-MeCOEt. Our results indicate t hat these systems induce the polymerization of styrene reaching a larg er conversion when the molar ratio MeCOEt/Ph2Zn = 1,0. According to si ze exclusion chromatography, SEC, studies of the polystyrene obtained using the Ph2Zn-MeCOEt showed unimodal curves and have molecular weigh t distribution narrower than those obtained using the Ph2Zn-H2O system , suggesting a more simple reaction system.
