1.前言热塑性弹性体(TPE)指的是在高温下像塑料一样能够塑化成型,在常温下具有橡胶弹性体功能的一类材料。已经提出各种各样分子结构的TPE在实际中使用。而且在各种分子设计的构思上也是多种多样。本文所讲的课题是TPE的结构和性质。从题目本身看,应该对各种TPE尽可能进行共性方面的论述。但是,到目前为止,还没有充分掌握每种TPE的结构和性质,所以搞不清用什么作为共性进行论述,只得以现在研究最多的苯乙烯系列的TPE知识为主,把用苯乙烯TPE得到的正在被系统化的基本概念推广应用到其它TPE上。
1. INTRODUCTION Thermoplastic elastomers (TPE) refer to a class of materials that can be plasticized at high temperatures like plastics and have the function of rubber elastomers at room temperature. TPE has been proposed for various molecular structures in practice. But also in a variety of molecular design concept is varied. The subject of this article is the structure and nature of TPE. From the point of view of the problem, we should try our best to discuss the commonalities of various TPEs. However, up to now, the structure and properties of each TPE have not been sufficiently grasped. Therefore, it is not clear what to use as a general description. Only TPE, the most studied styrene series, The systematic concept is being applied to other TPEs.
