摘要：

Amorphous isotropic poly(ethylene terephthalate) films were deformed under uniaxial-planar symmetry conditions at constant engineering stress close to and above the glass transition temperature. The structure of the crystalline phase is characterized in terms of orientation, size and organization of the crystalline blocks by X-ray scattering techniques. The orientation of the crystallographic axes and the size of the crystalline blocks are well rescaled by the macroscopic draw ratio, which is a function of the drawing temperature and the applied stress. The large-scale organization of the crystalline phase is not determined by the same parameter but changes mainly with temperature.
