Abstract Polyurethane-ureas(PUUs) were prepared from 4,4\'-methylenebis(cyclohexyl
isocyanate) and various diols including isosorbide. Isosorbide is starch-derived monomer
that exhibit a wide range of glass transition temperature and are therefore able to be
used in many applications. PUU was synthesized by a pre-polymer polymerization using
a catalyst. Successful synthesis of the PUU was characterized by fourier transform-infrared
spectroscopy. Thermal properties were determined by differential scanning calorimetry,
thermogravimetric analysis, and dynamic mechanical analysis. It was found that by tuning
isosorbide content in the resin, their glass transition temperature(Tg) slightly decreased.
Physical properties were also determined by tensile strength and X-ray diffraction. There
is no significant differences between petroleum-derived diol and isosorbide in XRD analysis.
Moreover, their physical and optical properties were determined. The result showed
that the poly(tetramethylene ether glycol)/isosorbide-based PUU exhibited enhanced tensile
strength, transmittance, transparency and biodegradability compared to the existing
diols. After 11 weeks composting, the biodegradability of blends increased in ISB-PUU.
The morphology of the fractured surface of blend films were investigated by scanning
electron microscopy. |
