    The dynamic mechanical analysis of epoxy-copper powder composites using azole compounds as coupling agents (1991)

    Notes: The dynamic mechanical properties of cured epoxy resin have been studied in which copper powder treated or untreated with azole compounds was used as fillers. The untreated fillers do not shift the glass transition temperature of the matrix polymer of the composites, whereas the storage modulus rises with increasing content of fillers. The application of azole compounds as coupling agents, which could react with both copper and epoxy resin, extended the polymer-filler interactions. The composite filled with copper powder treated with benzotriazole shows a strong reinforcement effect and high resistance to moisture.

    Notes: A flat-spring supported sample technique has been developed for studying the dynamic mechanical properties of a polymer in all its mechanical states, especially for materials with insufficient tensile strength for tensile mode test. The results obtained by this new technique show good agreement with the data from tensile mode tests for poly(ethylene terephthalate) and polystyrene. A high crystallization rate in temperature region 110-160°C for a quenched poly(ethylene terephthalate) and a secondary relaxation at the temperature of 100°C above Tg for a monodispersed polystyrene with a molecular weight of 3 × 105 could be measured quantitatively by the flat-spring supported polymer technique. This is an important improvement over the existing supported sample techniques.

    Dynamic mechanical analysis of sulfonated polyurethane ionomers (1992)

    Notes: Dynamic mechanical analysis, using a flat-spring to support the sample, was conducted to study the properties of polyurethane ionomers prepared from poly(epoxy chloropropane) as polyol. The effects of the soft segment length and ionization level on the properties were studied. For the unionized polyurethane, the soft and hard segments had good compatibility and little phase separation was found due to the high polarity of the polyol. For the shorter hard segment ionomers, as the ionization level increased, the matrix Tg rose due to the increase in the compatibility of hard and soft segments. For the longer ionized hard segment ionomers, the aggregating tendency of ion pairs enhanced phase separation. Quenching or annealing the samples showed that clusters existing in bulk materials did not dissociate below the degradation temperature and multiplets can dissociate or transform to clusters below 150°C.

    Reinforcement mechanism of polyester-fiber-reinforced rubber - A model study (1983)

    Notes: The reinforcement mechanism of polyester tire cord was studied by Fourier-transform infrared spectroscopy using various model compounds. Three model compounds representing the main chain of polyester and the terminal groups, namely carboxylic acid and hydroxyl groups, were used. Chemical reactions between these polyester models and an epoxy functional silane coupling agent were studied qualitatively as well as quantitatively. Among the many possible reactions, the reaction between the carboxylic acid and epoxy group was found to proceed readily. Kinetic studies of the major reactions also show quantitative differences in their activation energies as well as the rate constants. Based on the quantitative studies, we have estimated the expected rate of interfacial reaction at the heat treating temperature of polyester tire cord.

    Surface studies of polyimide thin films via surface-enhanced Raman scattering and second harmonic generation (1998)

    Notes: Two polyimides having the same backbone chemical structure and different pendant side groups at the 2- and 2′-positions of the diamine, the six methylene units capped with 4-cyanobiphenyl end groups and trifluoromethyl, were synthesized (6FDA-6CBO and 6FDA-PFMB). Surface-enhanced Raman scattering and surface optical second harmonic generation measurements show that after rubbing the major change in 6FDA-PFMB surface appears in the orientation of the dianhydride, which was originally planar, but becomes tilted with respect to the surface plane. In the case of 6FDA-6CBO, rubbing also causes the originally planar 4-cyanobiphenyls to tilt away from the surface and assume an azimuthally anisotropic distribution.
