Solvent Effect on the Polymerization of Methyl Metbacrylate Initiated by Hydridocarbonyltris- (triphenylphosphine) rhodium (I) -Carbon Tetrachloride

Abstract

The solvent effect on the polymerization of methyl methacrylate (MMA) initiated by hydrido-carbonyltris (triphenylphosphine) rhodium (I) -carbon tetrachloride was studied. The polymerization rate was found to decrease in the following order; DMSO>DMF>THF>benzene. When DMSO was used as a solvent, the concentration of DMSO had a great influence on the polymer yield and the composition curve of the copolymerization of styrene with MMA agreed with that of the ordinary radical polymerization.
