An Environmentally Benign Room Temperature Aqueous Homo- and Copolymerization of Styrene and Methylmethacrylate Catalyzed by [Cp2TiCl2]/NaBPh4
[Cp2TiCl2] has been found to be an effective precatalyst for room temperature aqueous homo- and copolymerization of methyl methacrylate and styrene in the presence of a cocatalyst, NaBPb4 and an emulsifier, sodium n-dodecyl sulfate. The polymers obtained are of high molecular weight with low molecular weight distribution. (C) 2009 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 47: 6496-6503, 2009
