中文摘要：

三元乙丙橡胶在使用过程中,受到光、氧、热和化学介质等外界因素的作用,会发生一定程度的老化,使其性能劣化、制品使用寿命缩短。综述了国内外三元乙丙橡胶（EPDM）老化研究的进展,指出了三元乙丙橡胶老化研究的发展方向。

英文摘要：

During outdoor applications,ethylene-propylene-diene monomer（EPDM） rubber can be degraded under the effect of light,oxygen,heat and chemical medium, which can deteriorate the bulk properties and reduce its service life.The research on EPDM aging was reviewed in this paper and the trend of development in EPDM aging studies was proposed.
