Abstract
A photoreactive plastic composition degradable by ultraviolet radiation, said composition consisting essentially of a photodegradable polymer having uniformly dispersed therein about 0.01-10% by weight of at least one photosensitizer. There is also provided a process for the preparation of the photoreactive plastic composition. The photoreactive plastic compositions are useful for making plastic articles, particularly plastic packaging materials.
