| 中文摘要 | the isothermal crystallization and melting behaviors of poly(propylene carbonate) end-capped with benzenesulfonyl/poly (vinyl alcohol) (ppc-bs/pva) blends over rich pva composition range were first investigated by differential scanning calorimetry (dsc). pps-bs/pva interaction parameter, chi(12), calculated from equilibrium melting temperature depression was -0.44, revealing miscibility of ppc-bs with pva in the melt and favorable interactions. the temperature dependence of crystallization rate constant at initial crystallization stage was analyzed using the modified lauritzen-hoffman expression. the chain width, a(0), the thickness of a monomolecular layer, b(0), the fold and lateral surface-free energies, sigma(e) and sigma, and the work of chain folding, q, for neat pva were first reckoned to be 4.50 angstrom, 4.78 angstrom, 76.0 erg.cm(-2), and 4.70 kcal.mol(-1), respectively. the values of sigma(e) and q for pva in ppc-bs/pva blends exhibited a maximum in the neighborhood of 10/90 ppc-bs/pv, respectively. |
