Abstract

We studied the kinetics and mechanism of the charge-transfer polymerization of methyl methacrylate (MMA) initiated with n-butyl amine (BA) and carbon tetrachloride (CCl 4) catalyzed by palladium dichloride (PdCl 2 or Pd II) in a dimethyl sulfoxide medium by using a dilatometric technique at 60°C. The rate of polymerization (R p) was a function of [MMA], [BA], [CCl 4], and [Pd II]. The kinetic data indicated a mechanism involving the possible participation of the charge-transfer complex formed between the {BA-Pd II} complex and CCl 4 or monomer in the polymerization of MMA. In the absence of either CCl 4 or BA, no polymerization of MMA was observed under these experimental conditions. R p was inhibited by hydroquinone; this suggested a free-radical initiation. © 2011 Wiley Periodicals, Inc.
