Various thio‐organotin compounds have been reacted with t‐butyl hydroperoxide in order to determine whether this oxidation can be responsible for the stabilizing capacity of some thio‐organotins towards polyolefin degradation. The kinetics of t‐butyl hydroperoxide disappearance, in the presence of thiotin compounds, shows different reactivity according to the structure of oranometallic reagent. Product analysis indicates organotin oxide, dialkyl disulfide and t‐butanol as major reaction products. The reactivity sequence towards hydroperoxide is the same as the order observed for polypropylene stabilization.
