    篇名/題名:Effect of nanoscale fully vulcanized acrylic rubber powders on crystallization of poly(butylene terephthalate): Isothermal crystallization
    摘要:Poly(butylene terephthalate) (PBT) was blended with nanoscale fully vulcanized acrylic rubber (FVAR) powders in a
    twin extruder, and the FVAR powders were dispersed well in PBT from scanning electron microscopy (SEM) and transmission
    electron microscope (TEM) investigation. The isothermal crystallization kinetics of PBT/FVAR blends were investigated
    by differential scanning calorimeter (DSC) and simulated by Avrami model. Equilibrium melting temperature was
    estimated by the nonlinear Hoffman–Weeks relation. The active energy (DE) and nucleation parameters (Kg) increased with
    the addition of FVAR, suggesting that FVAR particles hindered the crystallization; however more content FVAR had a
    lower DE and Kg because FVAR powders acted as heterogeneous nuclei in the nucleation of crystallization and facilitated
    the crystallization of PBT. The crystallization ability followed the order: PBT > PBT/FVAR6 > PBT/FVAR3 > PBT/
    FVAR1 when undercooling was considered.
