ABSTRACT
Fig. 5. Taking into account this result, the average rate of oxidation (Vi) in the induction period can be characterized by the ratio
The obtained value of Ll[02]i correlates well with the result of direct determination (obtained in Ref. 54), in which clearly purified PP was oxidized as a finely
grained powder under oxygen pressure ofPo2 == 150 torr (air) and a temperature of 92°C. The manometric instrument used in this study (54), possessed a 1000-time sensitivity over that on which the generalized curve (see Fig. 5) has been obtained.
