<p>In order to develop a new concrete repair method under cold and moist conditions, melt adhesion tests of carbon fiber sheet and cement mortar using thermoplastic epoxy resin were examined. Thermoplastic epoxy resins having controlled molecular weight were prepared by the addition of bisphenol A. Melt viscosity and tensile properties of the epoxy resins decreased with decreasing molecular weight. Higher adhesive strength was observed when the lower-molecular-weight resin was used. It was shown that the low melt viscosity of the epoxy resin plays an important role on achieving strong adhesion between carbon fiber sheet and mortar. </p>

<p>Polyurethanes are applied as artificial skin materials for medical simulators. There is a difference between human skin and artificial skin for simulators with respect to “puncture resistance.” Based on comments from medical doctors who perform puncture procedures in clinical sites, puncturing human skin is expressed as “low needle resistance,” whereas the artificial skin for simulators is expressed as “high needle resistance.” It is possible to practice medical procedures with a more realistic sensation if the artificial skin’s puncture resistance is brought closer to that of the human skin. In this study, sensory evaluations via needle suturing and quantitative evaluation via measuring devices were performed to clarify the relationship between the puncture resistance force and physical properties of three artificial skin samples for a suture training model made of polyurethanes. The composition and molecular structures of the materials were confirmed using Fourier transform infrared spectroscopy and nuclear magnetic resonance. The puncture resistance force measurements showed that Regina’s artificial skin: MODEL A was the lowest in three samples. Additionally, we discovered that low Young’s modulus and the amount of plasticizer contributed to the decreasing puncture resistance of MODEL A. This study proposes methods to combine sensory evaluation by humans and experimental data of the materials for the suture training model.</p>

<p>The thermal self-polycondensation of 4-(3,5-bis(4-aminophenoxy)phenoxy)phthalic acid, an AB₂ type monomer, proceeded successfully at 140°C to form a hyperbranched poly(amic acid). The subsequent chemical imidization of the poly(amic acid) afforded hyperbranched aromatic polyimides bearing acetylamide (<b>HBPI-Ac</b>) or imide terminal (<b>HBPI-Im</b>) groups. The formation of high molecular weight polymers was confirmed by gel permeation chromatography measurements using a light scattering detector. The resulting polymers exhibited good solubility and low solution viscosity, which is typical for hyperbranched polymers. The degree of branching of <b>HBPI-Ac</b> was determined to be 0.48. Moreover, the ¹H NMR measurement of the model phthalic acid compound at 120°C suggested that the formation of carboxyl anhydride units facilitated the amide bond formation, resulting in the hyperbranched poly(amic acid). <b>HBPI-Im</b> showed the temperature for a 5 % weight loss at 470°C, which was much higher than that of <b>HBPI-Ac</b> (400°C). <b>HBPI-Im</b> film, coated on a glass plate, became insoluble in amide solvents after heating at 280 °C for 10 min, indicating that it could be applied as a solvent-resistant and thermally stable coating in the microelectronics industry.</p>

<p>In this study, 4-butylaniline-impregnated resins (BuIRs) were prepared by soaking hydrophobic porous resins in aqueous solutions of 4-butylaniline hydrochloride. Rh(III) was successfully adsorbed by BuIRs from10 ppm Rh(III) solutions (6 M HCl). The quantitative desorption of Rh(III) accompanied with 4-butylaniline hydrochloride from BuIRs was also achieved by Soxhlet extraction using methanol. UV-Vis absorption measurements of Rh(III)-containing solutions showed that the equilibrium shift of Rh(III)-based species in HCl solutions is slow, and heating of the solutions is effective for equilibrating. The BuIRs obtained in this study effectively recovered the Rh(III) chloro-complex anion ([RhCl₆]^3－) from low Rh(III) concentration solutions, and can be useful in the Rh(III) recovery process.</p>
