| 中文摘要 | the miscibility and the isothermal crystallization kinetics for pbt/epoxy blends have been studied by using differential scanning calorimetry, and several kinetic analyses have been used to describe the crystallization process. the avrami exponents n were obtained for pbt/epoxy blends. an addition of small amount of epoxy resin (3%) leads to an increase in the number of effective nuclei, thus resulting in an increase in crystallization rate and a stronger trend of instantaneous three-dimensional growth. for isothermal crystallization, crystallization parameter analysis showed that epoxy particles could act as effective nucleating agents, accelerating the crystallization of pbt component in the pbt/epoxy blends. the lauritzen-hoffman equation for dsc isothermal crystallization data revealed that pbt/epoxy 97/3 had lower nucleation constant k, than 100/0, 93/7, and 90/10 pbt/epoxy blends. analysis of the crystallization data of pbt/epoxy blends showed that crystallization occurs in regime ii. the fold surface free energy, sigma(e) = 101.7-58.0 x 10(-3) j/m(2), and work of chain folding, q = 5.79-3.30 kcal/mol, were determined. the equilibrium melting point depressions of pbt/epoxy blends were observed and the flory-huggins interaction parameters were obtained. |
