The thermal stability of a series of organotellurium compounds was determined by thermogravimetric analysis and the stabilizing capacity of the most heat‐resistant compounds assessed in natural rubber, polyethylene, and polypropylene by measurement of the oxidative induction time (OIT). The most active compounds, bis[4‐(dimethylamino)phenyl]telluride ( 5 ) and bis[2,6‐dimethyl‐4‐(dimethylamino)phenyl]telluride ( 10 ) stabilized natural rubber considerably at the 1% level and even more so at the 2% level. A similar stabilizing effect of compound 5 was found in polyethylene and polypropylene at the 0.1% level. © 1996 John Wiley & Sons, Inc.
