高分子间相互作用的特点及意义

高分子间的相互作用与小分子间的相互作用有着显著的区别，导致高分子物质在凝聚态结构和诸多性能上明显地有别于小分子物质。本文就如下七个方面：特别强的高分子间相互作用、特殊的高聚物溶解过程、马克三角形原理、特征温度、特有的单链凝聚态、凝聚缠结和超分子体系来讨论高分子间相互作用的重要性及其对高聚物的结构和性能的影响。

The Speciality and Meaning of Interactions between Macromolecules

The difference of interactions between macromolecules and small molecules is obvious. As a result, the condensed states and the properties of macromolecules are quite different from that of small molecules. In this paper, the importance of interactions between macromolecules and its influence upon both structure and properties has been discussed in following aspects:the strong interactions between macromolecules, the peculiar dissolving process of polymer in solvent, Mark triangle principle, characteristic temperatures, the unusual single chain macromolecular condensed state, cohesive entanglement and supermolecular system.
