    Studies on understanding the extent of hydrogen bonding between urethane, urea, and polyether segments: comparison of experimental results and quantum mechanical calculations.

    The extent of hydrogen bonding between urethane and urea hard segments and polyether soft segments was studied using differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) spectroscopy. Model urethane and urea compounds were prepared and characterized. These models were then blended with polyether oligomers at different ratios. The change in melting peaks in both positions and enthalpies were used to measure the extent of hydrogen bonding in these systems. The DSC scans were compared with FTIR observation and also with quantum mechanical calculations.

    The presence of the hydrogen bonding between model urethane, ether and alcohol compounds were studied using quantum mechanical methods. Various conformations of hydrogen bonded pairs were obtained. The relative stability of model compounds with respect to their monomers was used as the basis of detecting hydrogen bonds. The relative shifts of the infrared absorptions of functional groups upon the formation of hydrogen bonds were observed in all structures. Thus, the quantum mechanical calculations can be a powerful tool for detecting hydrogen bonds in polymers.

    Incorporation of metal salts into polymeric materials leads to improvements in thermal, mechanical and electrical properties of the system. Depending on the structure and the oxidation state of the metal ion, these materials also display interesting optoelectronic properties. Silicone-urea copolymers containing various amounts of CoCl2.6H(2)O were prepared by solution blending. The level of metal incorporation ranged from 10% to 100% on molar basis. Products obtained were characterized by infrared spectroscopy, thermal analyses and stress-strain tests. In order to understand the mechanism of complex formation, quantum mechanical calculations were carried out on model 1,3-dimethylurea/Co(II) systems. Blends of 1,3-dimethylurea and CoCl2.6H(2)O were also prepared and analyzed by infrared spectroscopy.
