摘要

环状聚合物是理解聚合物分子结构和动力学之间关系的模型聚合物之一。综述了近年来纯环状聚合物、环状/线型聚合物共混物和环状聚合物衍生物的流变学研究进展。纯环聚合物由于不存在链端而表现出与线性聚合物不同的线性和非线性流变特性。环状聚合物中线性链的存在由于自发分子间环/线性螺纹的发生而敏感地影响流变性质。当蝌蚪形和哑铃形聚合物的分子中连接了环和线性链时，这种效应变得显著。

Rheological Properties of Ring Polymers and Their Derivatives

Ring polymers are one of the model polymers to understand the relationship between molecular architecture and the dynamics of polymers. This review summarizes the recent rheological studies on pure ring polymers, ring/linear polymer blends, and ring polymer derivatives. Pure ring polymers exhibit different linear and nonlinear rheological properties from linear polymers owing to the absence of chain ends. The presence of linear chains in ring polymers sensitively influences the rheological properties due to the occurrence of spontaneous intermolecular ring/linear threading. This effect becomes significant when a ring and linear chains are connected in a molecule for tadpole-shaped and dumbbell-shaped polymers.

期刊介绍： For the communication among the members, the journal of the Society of Rheology Japan, NIHON REOROJI GAKKAISHI (5 issues per year), was established in 1973 and it is the oldest journal on rheology in Asia. The journal contains original and review articles on rheology and related topics, information for all SRJ events, and reports of domestic/overseas meetings. Articles in Japanese as well as in English are considered for publication, not only from the members but also from the researchers outside. Papers from new emerging areas of the field are particularly welcome. The electronic version of the articles is available via the internet with an open access policy.
