Early transition metal catalyzed aqueous emulsion copolymerization: Copolymerization of styrene and methyl methacrylate by Cp2TiCl2 in aqueous medium
An early transition metal metallocene compound, Cp2TiCl2, with an anionic surfactant, sodium n-dodecyl sulfate (SDS), as emulsifier has been found to be an effective catalyst for copolymerization of a polar monomer, methyl methacrylate (MMA), and an alpha-olefin, styrene, and afford high molecular weight copolymer with low molecular weight distribution.
