Abstract

Results from previous publications of the series are interpreted and discussed in terms of a reaction scheme. Probabilities of the different non‐terminating reactions of α‐alkoxyalkylperoxy radicals during the autoxidation of solutions of poly(oxytetramethylene) 10^−2^ g cm^−3^ ≤ c ≤ 6.10^−2^ g cm^−3^ were determined as follows: for the H atom abstraction = 0,2–0,4, for the monomolecular decomposition (reference) = 1, and for the non‐terminating bimolecular reaction = 7–10.
