✦ Synopsis

The addition of 0.17-0.50% of bis [4-(dimethylamino)phenyl]telluride to the thermoplastic elastomer PACREL significantly improved tensile strength and elongation at break in unaged and oven-aged samples. Chemiluminescence measurements showed that the organotellurium compound considerably prolonged the induction period of thermooxidation of the material and drastically reduced the total luminescence intensity of unaged and aged samples. These results indicate that the improved mechanical properties of diaryl telluride stabilized PACREL can be attributed to the antioxidative (peroxide decomposing, chain breaking) properties of the stabilizer.
