Study on Molecular Rheology Using Some Model Polymers Based on Precise Synthesis

It is essentially important for understanding of viscoelastic properties of polymers to use "model polymer" with well-defined molecular structure. In order to synthesize the model polymers, one of the precise polymerization techniques, living anionic polymerization, was used for all the polymers in this study. Preparation, characterization, and viscoelastic properties of several model polymers such as highly-purified ring polymers, ring-based polymers, ring block copolymers, and a series of poly(4-n-alkylstyrene)s are introduced and the molecular architecture-rheology relationships for the model polymers are investigated and discussed.
