We review coarse-grained models of meso-scale structures for dynamics and rheology in polymeric systems. Polymeric systems often exhibit hierarchically self-assmebled structures from micro-scale structures to macro-scale structures. The rheological behavior of polymeric systems reflect the dynamics of hierarchical structures. In meso-scale coarsegrained models, characteristic structures with characteristic time and length scales (such as the end-to-end vectors and density fields) are utilized as the basic units. Such coarse-grained models are useful both for numerical simulations and analyses of experimental data. In this article, we consider basic properties and applications of several meso-scale coarsegrained models developped by the author, including the dynamics models for calculation of rheological properties, the structural models for polymeric solids, and the models for block copolymer micelles.
