## Abstract Autoxidation of poly(oxytetramethylene) at 25°C was studied by means of radiation induced initiation of chloroformic solutions of the polymer. It includes primary oxidative degradation reactions characterized by main chain scissions and subsequent formation of ethylene, formate groups,
## Abstract The kinetics of the production of ethylene during the radiation induced autoxidation of poly(oxytetramethylene) were determined in chloroform solution at 25°C. It was found that the primary oxidative degradation of the polymer generating ethylene is part of a chain reaction process.
