The structure–properties relationship is used as a basis in the description of experimental methods for the characterization of the topological structure of polymers. The possibilities of evaluating the molecular weights, molecular-weight distribution (MWD), and branching from the data on rheological, relaxation, and other physical properties are examined. From this standpoint, crosslinked polymers and equilibrium physical networks, as well as topologically linked macromolecules (polyrotaxanes and polycatenanes), are analyzed. Methods for the calculating relaxation spectra (RSs) from the experimental data are discussed.

聚合物的体系结构：拓扑结构与属性的关系

在描述表征聚合物拓扑结构的实验方法时，结构-性质关系被用作基础。考察了评估分子量，分子量分布（MWD）以及从流变学，弛豫和其他物理特性数据中得出分支的可能性。从这个角度出发，分析了交联的聚合物和平衡物理网络，以及拓扑连接的大分子（聚轮烷和聚catenanes）。讨论了根据实验数据计算弛豫谱的方法。
