Abstract

The crystalline structure evolution of poly(butylene terephthalate)/poly(carbonate) (PBT/PC) during stretching was investigated by in situ synchrotron wide-angle X-ray scattering (WAXS) and small-angle X-ray scattering (SAXS) at 70 °C. The WAXS results demonstrated that the crystallinity and crystallite size (D₁₀₀) decrease with deformation. The α-β transition was observed during the deformation of PBT/PC blends. The orientation degree of the PBT (100) diffraction increases with strain in the PBT/PC blends. The SAXS data showed that PC is located in the interlamellar region of PBT for the undeformed samples. A structure model was proposed to describe the stretching-induced structure evolution of the PBT/PC blends.
