摘要：
The miscibility and crystallization kinetics of the blends of poly(ε-caprolactone) (PCL) and bezoxazine (B-m) resin was investigated by differential scanning calorimetry (DSC) and polarized optical microscopy (POM). It was found that PCL/B-m blends were miscible in the melt. Thus the blend exhibited a single glass transition temperature (Tg), which increased with increasing B-m composition and the crystal equilibrium temperature (T m°) depressed with the addition of B-m from the Hoffman-Weeks equation analysis. The freezing crystallization temperature (Tfc) for the nonisothermal crystallization on the cooling process, and the spherulitic growth and overall crystallization rates of PCL for the isothermal crystallization were depressed with the addition of B-m component, attributing it to the dilution of PCL concentration due to the addition of B-m.
