摘要：
A styrene-arsenic sulphide complex in DMSO at 85 +/- 0.1-degrees-C initiates radical polymerization of methyl acrylate over 90 min under a N2 blanket. Conversion reaches 83% without gelation and results in the formation of polymer having average degree of polymerization 710. Analysis of the kinetic data (up to 29% conversion) indicates that the system follows ideal kinetics. The reaction is retarded by hydroquinone. The overall activation energy and value of k(p)2/k(t) are 96 kJ mol-1 and 6.9 x 10(-3) litre mol-1 s-1, respectively.
