摘要
高分子的长链结构决定高分子材料的特殊性质。长链结构的显著特征是熵弹性,使高分子材料在强度、弹性模量、形变响应方面不同于金属材料和无机材料,从而导致高分子材料的独具的橡胶态。"高分子物理学"研究的主要对象是长链分子,文中以高分子长链结构和凝聚态结构为逻辑起点,根据长链结构的存在状态与高分子特殊的链段运动单元之间的关系,阐述了高分子独有的橡胶态、松弛特性及流动中明显的粘弹特性,体现出高分子长链结构在研究"高分子物理学"中的主线作用。
The special properties of the polymer materials are affected by their structures. Long-chain structure, or entropy elasticity, is one of features of polymers, which lead to rubber state polymers with some characteristics different from metal and inorganic materials such as responses of strength, modulus and deformations. The main objectives of ＂ Polymer Physics＂ were to study the long-chain structure. Stating with long-chain and condensed structures of polymers, the rubber state, relaxation and viscoelasticity of polymer were depicted according to effects of long-chain state on the segmental motion, by which the main-clue role of long-chain structure in ＂Polymer Physics＂ was displayed.
