HINDERED PHENOLS - MODELING INHIBITION-MECHANISM

The inhibition mechanism of hindered phenols in polymers and low-molec ular compounds can be studied by using the procedures developed to stu dy complicated processes of chain oxidation and inhibition in hydrocar bon materials. At each temperature (mechanism strongly depends on temp erature and other factors) the key reactions of antioxidant actions we re identified and corresponding kinetic parameters determined. The ana lysis showed how the effectiveness of hindered phenoles changes as a f unction of temperature.
