Progress in Study of Polymer Degradation Behaviors and Mechanisms in Various Environment Conditions

总结了有关高分子材料在环境因素作用下老化研究的历史与现状,阐述了环境场(如光、热和化学介质)对高分子老化的影响,提出了材料老化的一些主要机理。在探讨了一些新研究手段的发展和取得的成果的基础上,进而展望了高分子材料老化及防护措施的研究动向和发展趋势。

This paper has reviewed the study of polymer degradation in various environment conditions today. Discussed the effect of several environment factors, such as photo, thermal and chemical media, on the polymer ageing; and listed some mainly degradation mechanisms introduced in recent years. At the same time, reported the newly research results by means of some updated techniques and overviewed the trend of research about polymer degradation.
