Abstract
It was shown that alpha-relaxation in highly oriented polyethylene wit h a fibrillar structure (fibers) causes breaks in the Arrhenius depend ences for the oxidation rate and the radiation yield of a decrease in fiber strength. The character of these breaks depends on die dose rate and is connected with unfreezing of die mobility of unfolded tie chai ns whose concentration in oriented fibers is rather high.
