高聚物材料由于受到热、光、氧、机械力等外界因素作用下,引起结构改变,性能变坏,这些现象早被人们当作重要问题来研究,因为合成高聚物有一个通病即是稳定性较差,常是怕热、怕光、怕氧等等,容易老化,因而若不提高高聚物的稳定性,是无法考虑大量生产的。关于高聚物稳定性方面的研究大致可分为二类:1)加入各种稳定剂,以提高高聚物的稳定性,即稳定作用的研究,由于它密切关系到生产实践,因此一直是人们集中注意力的方面。这已进行了大量工作,合成高聚物所以有今日那样的规模发展,是和稳定作用研究所取得的成果分不开,几乎今日大量生产的各种高聚材料,没有不含有一种或数种稳定剂的。2)研究高聚物本身在外界因素影响下的化学及结构变化,近十几年来,开始注意到高聚物链结构对稳定性的关系,这方
Due to heat, light, oxygen, mechanical forces and other external factors, high polymer materials cause structural changes and deteriorate their performance. These phenomena have long been considered as an important issue because synthetic polymers have a common problem Poor stability, often afraid of heat, fear of light, fear of oxygen, etc., easy to aging, so if you do not improve the stability of polymers, it is impossible to consider mass production. Studies on the stability of polymers can be broadly divided into two categories: 1) The addition of various stabilizers to improve the stability of the polymer, ie the study of stabilization, has been, since it is closely related to the production practice, People focus their attention. Much work has been done to synthesize polymers so that today’s scale development is inseparable from the achievements made in the study of stabilization. Almost all kinds of high-polymer materials mass-produced today do not contain one or more Stabilizing agent. 2) To study the chemical and structural changes of polymer itself under the influence of external factors, and in the recent ten years, we have noticed the relationship between polymer chain structure and stability.
