Pk. Srivastava et Sk. Upadhyay, Kinetics of Pd-II-catalyzed polymerization of methyl methacrylate by triethanolamine in the presence of CCl4, INT J CH K, 32(3), 2000, pp. 171-177
Polymerization of methyl methacrylate (MMA) with triethanolamine (TEA) and
carbon tetrachloride has been investigated in the presence of PdCl2 and in
a dimethylsulfoxide (DMSO) medium by employing a dilatometric technique at
60 degrees C. The rate of polymerization has been obtained under the condit
ions [CCl4]/[TEA] less than or equal to 1. The kinetic date indicate the po
ssible participation of the charge-transfer complex formed between the {ami
ne-Pd-II} complex and CCl4 in the polymerization of MMA. In the absence of
either CCl4 or amine, no polymerization of MMA was observed under the prese
nt experimental conditions. The rate of polymerization was inhibited by hyd
roquinone, suggesting a free-radical initiation. (C) 2000 John Wiley & Sons
