PHOTODEGRADABLE PLASTIC COMPOSITION

摘要

A thermoplastic composition is provided which is degradable under the action of sunlight and/or ultraviolet light. The thermoplastic composition comprises a thermoplastic polymer, a first transition metal compound which may be a complex, a second transition metal compound and an aromatic ketone. The thermoplastic polymer preferably comprises an olefin such as polyethylene, ethylene copolymers, polypropylene, polystyrene or polyurethane. The first transition metal compound preferably comprises an iron compound such as iron stearate. The second transition metal preferably comprises copper stearate and the aromatic ketone preferably comprises benzophenone.
