内容記述 | Four types of segmented polyurethanes with systematically varying blockness of hard segment were prepared. The dynamic viscoelastic properties of the segmented polyurethanes were studied in a wide range of temperature. These segmented polyurethanes were prepared by prepolymer technique using polyoxy tetramethylene glycol (PTMG) (Mn=1000 and 2000) and 4, 4'-diphenylmethanediisocyanate as starting materials and hydrazine and ethylenediamine as chain extenders. The samples were studied at a frequency of 110 Hz by Vibron DDV III-B. Differential scanning calorimetry (DSC) and infrared spectroscopy were also studied. These segmented polyurethanes showed tanδ maxima at two temperatures (-120℃ and -50℃). As the hard segment concentration was increased, main dispersion shifted to a lower temperature, its height of tanδ peak decreased and its width widened. As the moleculare weight of PTMG was increased, main dispersion shifted to a lower temperature. Storage modulus E' in a series of PTMG 1000-HD was increased as hard segment concentration was increased, but E' in a series of PTMG 2000-HD and -EDA were not affected. The dispersions were interpreted in terms of molecular motion and the difference of composition of segmented polyurethanes. | |||||
