Notes:
Abstract Arsenic sulfide interacts with styrene to form a complex which in DMSO at 80±0.1°C under N2 atmosphere, initiates radical polymerization of acrylonitrile. The kinetic equation of the system isR p ∞ [complex]0.5 [AN]. The value ofk p 2 /k t and energy of activation for the system are computed as 5.0×10−1 l mol−1 s−1 and 98.2 kJ mol−1, respectively. The polymerization is retarded by hydroquinone. The effect of polar and non-polar solvents has also been discussed. A possible mechanism for the reaction has also been proposed.
