| Research Abstract |
In this work, theories of dielectric and mechanical responses of polymers were constructed to understand experimentally observed response behavior of polymeric systems under flow. We constructed the anisotropic mobility model for dielectric and mechanical responses of polyisoprene under shear (the rheo-dielectric function and the orientation-dependent storage and loss moduli), which relates the response behavior to the molecular motion of polymer chains. We also showed that the shear-thickening behavior of associative polymer solutions can be also explained by the anisotropic motion.
