| Research Abstract |
We focused on precisely-controlled “ideal” polymer networks prepared by the “module building” method, and investigated the structure-property relationship on fundamental problems of rubber elasticity as well as polymer physics. With the aid of various kinds of experimental methods, such as small-angle neutron scattering (SANS), dynamic light scattering (DLS), small-angle X-ray scattering (SAXS), tensile measurements, rheology, swelling/shrining measurements, differential scanning calorimetry (DSC), infrared spectroscopy (IR), and computer simulation, we carried out intensive studies to elucidate the structure-property relationship of not only Tetra-PEG gels but also natural rubbers, phenol resins, threadlike micelles, and other systems. We succeeded in formation of precisely-controlled polymer network science.
