抄録

Polycarbonate-based polyurethane elastomers (PUEs) were prepared from poly(carbonate) (PC) glycol baring the number of methylene unit of 3-10. Aggregation structure and mechanical properties of these PUEs were investigated by differential scanning calorimetry (DSC), wide angle X-ray diffraction (WAXD) and dynamic viscoelatic measurement. The difference in the glass transition temperature of polyols (ΔTg,polyols) and Tg,PUEs (ΔTg) increased with increasing methylene chain length, indicating the degree of microphase separation became weaker with increasing methylene chain length. Magnitude of dynamic storage modulus (E') around rubbery plateau region in the E' curve decreased with increasing methylene chain length due to the change in microphase-separated state and flexibility of the PC glycols.
