Abstract
The thin films of miscible Polybutylene adipate)/Polyvinyl chloride (PBA/PVC) 6/4 blend under uniaxial drawing behavior was studied by wide angle X-ray diffraction (WAXD), small angle X-ray scattering (SAXS) and grazing incidence wide angle X-ray scattering (GIWAXS). We study crystals orientation of polymorphic PBA crystals through different draw ratios. The polymorphic phase transition of PBA only depends on temperature and it does not change under strain. The c-axis parallels to the stretching direction at low drawing ratios on both PBA crystals of alpha-and beta-crystals. In contrast, the b-axis of the PBA alpha-crystal was oriented parallel to the stretching direction and the a-axis of the PBA beta-crystal was oriented parallel to the stretching direction at high drawing ratios.
