PHOTODEGRADABLE POLYETHYLENE COMPOSITION CONTAINING POLY(4-METHYLPENTENE) AND A PHOTOSENSITIZER

摘要

Polyethylene contains poly(4-methylpentene-1) and a photosensitiser such as iron stearate or p-lauryl acetophenone. The combination of the two additives renders the composition more liable to photodegradation than when either additive is used alone.
