Abstract
Thermal stability of low density polyethylene stabilized with different diamine compounds: N-phenyl-1-naphtyl-amine, N-cyclohexyl-N’-phenyl-p-phenylen-diamine, N-(1,3-dimethyl-butyl)-N’-phenyl-p-phenylen-diamine and N, N’-di-(1,4-dimethylpentyl)-p-phenylen-diamine was investigated by chemiluminescence method. Kinetic parameters depicting the progress in thermal degradation at various temperatures, concentrations and irradiation doses were calculated. Energetic considerations on thermal stability induced by diamine presence are commented and antirad effect of this kind of compounds is emphasized. Keywords: low density polyethylene, diamine compounds
