Prooxidant additives represent a promising solution to the problem of the environment contamination with polyethylene film litter. Prooxidants accelerate photo- and thermo-oxidation and consequent polymer chain cleavage rendering the product apparently more susceptible to biodegradation. The question not fully resolved remains the biodegradation itself, its mechanism and especially the factors influencing the time-frame in which it can occur. The presented review is aimed to provide comprehensible information for both microbiologists and polymer scientists, who need participate in the research leading to an understanding of the microorganism action on the oxidized polyethylene and to design of new materials.
促氧化剂添加剂是解决聚乙烯薄膜垃圾造成环境污染问题的一种很有前景的解决方案。促氧化剂会加速光氧化和热氧化以及随之而来的聚合物链断裂，使产品显然更易被生物降解。尚未完全解决的问题仍然是生物降解本身、其机制，尤其是影响其发生时间框架的因素。本综述旨在为微生物学家和聚合物科学家提供易于理解的信息，他们需要参与相关研究，以了解微生物对氧化聚乙烯的作用并设计新材料。
