Large Deformation of Polycarbonate Near the Glass Transition Temperature. (9999)

Inoue, Tadashi, Okamoto, Hirotaka, Osaki, Kunihiro

The stress and the birefringence of bisphenol A polycarbonate were measured at 151 degrees during an elongation at constant speed (initial rate of elongation, e(o) = 1.0x10(-4) -7.4x10(-3)/S). The...

Viscoelasticity and Morphology of Soft Polycarbonate as a Substitute for Poly(vinyl chloride) (FUNDAMENTAL MATERIAL PROPERTIES-Molecular Rheology) (2001)

Inoue, Tadashi, Watanabe, Hiroshi, Osaki, Kunihiro

The soft polycarbonate resins, SPC, were newly developed as a substitute for soft poly(vinyl chloride). The soft polycarbonates are multiblock copolymers composed of bisphenol A polycarbonate, PC,...

Nonlinear Rheology and Flow-Induced Structure in a Concentrated Spherical Silica Suspension (FUNDAMENTAL MATERIAL PROPERTIES-Molecular Rheology) (2000)

Watanabe, Hiroshi, Inoue, Tadashi, Osaki, Kunihiro

In hard-sphere suspensions of solid particles, the stress has the Brownian (thermodynamic) and hydrodynamic components σB and σH, the former reflecting the anisotropy of the particle distribution...

Rheo-Dielectric Behavior of Oligostyrene and Polyisoprene (FUNDAMENTAL MATERIAL PROPERTIES-Molecular Rheology) (1999)

Watanabe, Hiroshi, Inoue, Tadashi, Osaki, Kunihiro

Flow effects were examined for dielectric behavior of oligostyrene (OS; M = 950) and cis-polyisoprene (PI; M = 8200). OS-1 has monomeric dipoles perpendicular to its backbone and the terminal...

Nonlinear Viscoelasticity of Amorphous Polymers in the Vicinity of the Glass Transition Temperature (FUNDAMENTAL MATERIAL PROPERTIES-Molecular Rheology) (1998)

Inoue, Tadashi, Watanabe, Hiroshi, Osaki, Kunihiro

Nonlinear viscoelasticity of atactic polystyrene around the glass transition was studied by means of constant rate elongation. The strain-induced birefringence and the stress were simultaneously...

Molecular Rheology of Glassy Polymers (FUNDAMENTAL MATERIAL PROPERTIES-Molecular Rheology) (1997)

Inoue, Tadashi, Matsui, Hiroto, Watanabe, Hiroshi, Osaki, Kunihiro

Molecular origin of the viscoelasticity around the glass transition zone is investigated by means of dynamic birefringence and dynamic viscoelasticity measurements. The present study show that the...
