    Notes: The adhesive joint strength behavior of vulcanized rubbers with epoxy adhesives during the ultraviolet (UV) treatment of rubber surfaces has been studied. The change in rubber surfaces and the interphase layer structure of joints has been investigated. A model for the joint strength behavior is suggested, with which one can predict the appropriate use of UV treatment of rubber surfaces to improve the joint strength. © 1996 John Wiley & Sons, Inc.

    Notes: IR transmission and Raman spectra of toluylene diisocyanate and hexamethylene diisocyanate and IR spectra of diphenylmethane diisocyanate, partially polymerized diphenylmethane diisocyanate, and polyisocyanurate were obtained. Toluylene diisocyanate and partially polymerized diphenylmethane diisocyanate form associates in the liquid state, which leads to anomalous intensity changes and a frequency shift to the νas (NCO) band in the spectrum of the treated rubber surface with time. The associate formation influences positively the properties of diisocyanates as rubber-surface modifiers for adhesion. © 1994 John Wiley & Sons, Inc.

    Notes: The glow discharge plasma treatment of EPDM-40 rubber has been studied using the IRMATR spectroscopy. A mathematical model for the kinetics of rubber surface oxidation processes has been suggested. The interrupted plasma treatment was proposed as the most efficient technique of polymer surface activation. It was noted that the rubber oxidation processes occurs during the contact with air after the plasma treatment, but not during the discharge. © 1993 John Wiley & Sons, Inc.

    Notes: Raman spectra of antimony trichloride in various phases and in crystals of complexes with naphthalene and p-xylene were measured. Normal coordinate analyses with different approximations for the potential energy matrix of SbCl3 were performed. The frequencies of lattice modes and half-periods of rotational librations of the SbCl3 molecule were determined. The non-diagonal elements of the potential energy matrix of AB3 molecules (in particular SbCl3) were shown to be insensitive to the intermolecular interaction. A normal coordinate analysis for SbCl3 intramolecular vibrations can be made using as an approximation only the diagonal part of the potential energy matrix for calculating the parameters of intermolecular interaction, which significantly simplifies the calculation and gives sufficient accuracy.

    Notes: The Raman spectra of trihalides of the Fifth Group, BiCl3, AsCl3, AsBr3, SbBr3 and PCl3, in the gas, liquid and solid were obtained. A normal coordinate analysis was performed. The intermolecular force constants were calculated from variations of the intramolecular force constants of the molecule during the phase transition. The half-periods of librations in the liquid and lattice frequencies in the crystal were calculated and the lattice spectrum of the crystal was interpreted. It is shown that for a heavy central atom the calculation of intermolecular force constants may be performed in the approximation of a diagonal potential energy matrix. For a light central atom such an approximation may be used only for estimates. In this case the use of a complete potential energy matrix of a molecule is necessary for an accurate calculation.

    Notes: The Raman spectra of bimolecular complexes crystals of antimony trichloride with benzene, diphenyl and phenanthrene were studied at 77 K. A group theoretical analysis and normal coordinates analysis of the antimony trichloride vibrations in complexes was made. The variation of force field with the gas-crystal phase change parameters of intermolecular interaction was defined. The interpretation of the lattice mode region was accomplished.
