摘　　要：聚乙烯(PE)中添加助氧化剂是解决废弃PE薄膜环境污染问题的一种有效方法。助氧化剂通过促进光和热降解导致聚合物分子链断裂而使塑料制品更易于生物降解。本文对近年来有关PE膜的氧化反应与微生物降解的研究进展进行了综述。Prooxidant added in polyethylene is a promising solution to the problem of the environment contamination with polyethylene film litter. Prooxidants accelerate photo- and thermo-oxidation and consequently polymer chain cleavage renders the polyethylene product apparently more susceptible to biodegradation. The advances in oxidation and biodegradation of PE film are reviewed in this paper.
