摘要： The oxidation of a high polymer such as polyvinyl chloride or polyolefin, which oxidation causes cleavages of carbon-carbon bonds in the main chains thereof to degrade the high polymer into lower molecular weight compounds, is remarkably accelerated when the high polymer is impregnated with a halogenated compound having a carbonyl group or carbonyl groups and exposed to sunlight or is irradiated with ultraviolet radiation in an ambient atmosphere of oxygen or a gas containing oxygen. This acceleration of the oxidation makes possible easy destruction of a shaped article made of such a high polymer.
