Polymerization of methyl methacrylate (MMA) with triethanolamine (TEA) and carbon tetrachloride has been investigated in the presence of PdCl 2 and in a dimethylsulfoxide (DMSO) medium by employing a dilatometric technique at 60°C. The rate of polymerization has been obtained under the conditions [CCl 4 ]/[TEA] ≤ 1. The kinetic date indicate the possible participation of the charge‐transfer complex formed between the {amine–Pd II } complex and CCl 4 in the polymerization of MMA. In the absence of either CCl 4 or amine, no polymerization of MMA was observed under the present experimental conditions. The rate of polymerization was inhibited by hydroquinone, suggesting a free‐radical initiation. © 2000 John Wiley & Sons, Inc. Int J Chem Kinet 32: 171–177, 2000
