| Abstract: | The crystallization behavior and crystal morphology of the poly(trimethyl terephthalate) (PTT)/poly(butylene terephthalate) (PBT) blends were investigated by means of differential scanning calorimetry (DSC), wide angle X‐ray diffraction (WAXD) and polarized light microscopy (PLM) techniques. It was found that the two components crystallized simultaneously in the crystalline regions. The degree of crystallinity changed with PTT content. Crystalline properties were worse when the ratio of PBT and PTT contents was close to 50:50, but were better when PBT content was greatly different from PTT content. |
