Abstract

Ruthenium trichloride (RuCl3 or RuIII) catalyzed polymerization of methylmethacrylate (MMA) initiated with n-butylamine (BA) in the presence of carbon tetrachloride (CCl4) by a charge-transfer mechanism has been investigated in a dimethylsulfoxide (DMSO) medium by employing a dilatometric technique at 60°C. The rate of polymerization (Rp) has been obtained under the conditions [CCl4]/[BA] ≤ 1 and [CCl4]/[BA] ≥ 1. The kinetic data indicate the possible participation of the charge-transfer complex formed between the amine-Ru III complex and CCl4 in the polymerization of MMA. In the absence of either CCl4 or BA, no polymerization of MMA is observed under the present experimental conditions. The rate of polymerization is inhibited by hydroquinone, suggesting a free-radical initiation.
