A styrene‐arsenic sulphide complex in DMSO at 85 ± 0.1°C initiates radical polymerization of methyl acrylate over 90 min under a N 2 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 2 p / k t are 96 kJ mol −1 and 6.9 × 10 −3 litre mol −1 s −1 , respectively.
