高分子单链凝聚态由于链内链结构单元间存在范德华吸引作用 ,高分子链呈打圈链构象 ,而多链凝聚态由于链内链单元间的吸引作用被与相互穿透的近邻链的单元间吸引作用所屏蔽 ,高分子链呈高斯链构象。本文简要介绍单链凝聚态试样的制备方法 ,单链单晶体、单链玻璃体、溶胀的单链高弹态拉伸等的实验观察 ,并提出从单链凝聚态到多链凝聚态的转变过程问题 ,即高分子线团的相互穿透过程 ,目前还缺少基础了解。
Macromolecule single-stranded condensed state due to van der Waals attraction between the chain-chain structural units, the polymer chain was circling chain conformation, and multi-chain condensed state due to the chain of inter-chain units are attracted to the mutual penetration of the adjacent chain Shielded by the attraction between the units, the polymer chains were Gaussian chain conformation. In this paper, the preparation methods of single-stranded condensed matter sample, single-stranded single-crystal, single-stranded glass body and swelling single-stranded high-elastic tensile test are briefly introduced, and the transition from single stranded condensed state to multi-stranded condensed state The problem, that is, the process of penetrating polymer threads, is still lacking in basic understanding.
