Polymer complexes—X. Polymerization of methyl methacrylate in the presence of some transition metal chlorides☆

Polymer complexes of methyl methacrylate with some transition metal chlorides were prepared and characterized by elemental analysis, i.r. and electronic spectroscopy. The rates of polymerization of methyl methacrylate in the absence and in the presence of metal chlorides were studied. The activation energies of the polymerizations were calculated.
