    Ring polymers are model polymers that do not have chain ends, and elucidating the correlation between their structure and physical properties is an important issue in the field of polymer physics. In this study, we experimentally examined the effects of linear chains in ring polymers on their viscoelasticity. The shape changes in the viscoelastic spectra of high molecular weight linear polystyrene (PS) mixed with low molecular weight linear PS, ring PS, and dumbbell-shaped PS, confirmed the molecular picture of enthalpy-driven spontaneous penetration of linear chains into ring chains.

  • Grant-in-Aid for Scientific Research(B)，2019.04 - 2023.03，Relaxation behavior of polymer glass below glass transition temperature

    We investigated rheological and relaxational properties of glassy polymers by using experiments, simulations, and theoretical analyses. We paid attention to the low temperature region below the glass transition temperature. We performed experiments and simulations to model polymer glass systems with simple structures, and showed that the time-temperature superposition works for rheological properties. In experiments, we also showed that the functional form of the rheological relaxation is not sensitive to the aging. At the low temperature region, glass formers show strongly collective motions. We successfully modeled such collective motions by using the concept of the transient potential.
