Polymer Degradation And Stability

Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology.

Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal.

However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.

《聚合物降解与稳定性》主要研究降解反应及其控制，这是现代聚合物技术众多不同方面从业人员的主要关注点。

在加工过程中，当聚合物受到热、氧气和机械应力时，以及在材料的使用寿命期间，当氧气和阳光是最重要的降解剂时，就会发生劣化反应。在更专业的应用中，降解可能是由高能辐射、臭氧、大气污染物、机械应力、生物作用、水解和许多其他影响引起的。如果要继续推进聚合物技术和应用，就必须了解这些反应和稳定过程的机制。因此，报告此类调查是本期刊的主要功能。

然而，聚合物技术也有新的发展，降解过程在其中找到了积极的应用。例如，现在已有光降解塑料，聚合物产品的回收利用将变得越来越重要，降解和燃烧研究涉及定义与聚合物材料相关的火灾危险，而微电子行业在制造电路时极其依赖于聚合物降解。聚合物性能也可以通过固化和接枝等工艺得到改善，这些工艺的化学性质可能与其他情况下导致物理损坏的化学性质密切相关。
