Effect of various triazine derivatives on the thermal oxidative degradation of isotactic polypropylene

摘要

AbstractA number of triazine derivatives, mostly aryloxy‐s‐triazines, were prepared, and the effects of these compounds on the thermal oxidative degradation of isotactic polypropylene were examined by conventional oxygen uptake. Almost all triazine derivatives prepared showed a more or less inhibitive effect on the degradation of the polymer. Among them, α‐ and β‐napthyloxy‐s‐triazines were found to be excellent inhibitors. On the basis of the results obtained, the relationship between inhibitive effect and the structure of the triazine derivatives
