Abstract

Three half-metallocene ruthenium(III) complexes, [(Cp∗RuCl₂)PPh₂R] (R = C₆H₄-OCH_3,C₆H_5, and C₅H₅N were prepared. These Ru(III) complexes polymerized MMA successfully via ATRP in the absence of any reducing agent or free radical initiator. All of three complexes produced a linear relationship between ln[M_n]₀/[M_n] versus the reaction time and the living properties through a linear increase in molecular weight versus conversion. Especially, well-defined PMMA and high initiation efficiency were obtained in the presence of 10 ppm catalysts.
