The rate of thermal decomposition of azobisisobutyronitrile (AIBN) dissolved in xylene was investigated alone and in the presence of tin(IV) chloride over the temperature range of 90–107°C. It was found that the decomposition rate of AIBN increases linearly with increasing concentration of tin(IV) chloride, which suggests the formation of an activated complex between AIBN and tin(IV) chloride. A parallel reaction mechanism is proposed to describe the kinetic behavior. The Arrhenius relationships of rate constants were also obtained.
