Title: THE OXIDATIVE DEGRADATION OF LARGE MOLECULES

Abstract

Oxidative degradation studies were made on several polymeric materials. Polyethylene, both low and high density, shows a slower rate of reaction for the Ziegler type (high density). The rate data can be interpreted by the Elovich equation for heterogeneous reaction at a gas solid interface. In a similar manner polystyrene and deuteropolystyrenes were studied both by carbonyl development and oxygen adsorption. The results indicate a free radical mechanism via peroxide formation. Owing to the free radical nature of the process, the introduction of radicals by the irradirtion of polymers with gamma radiation from Co/sup 60/ was undertaken. (auth)
