This work is devoted to a study of the properties of copolymers of polypropylene with a content of octene units of 1.5–8.4 mol%. A study was made of the kinetics of oxidation of nascent specimens of polypropylene and its copolymers with octene at temperatures of 90–130°C. At all temperatures, both the oxidation rates and the induction periods of oxidation depend extremally on the composition of the copolymer. It seems that the observed effects are connected with change in the chemical or physical structure of the amorphous regions.
