The two dimensional Wide Angle X-ray Scattering (WAXS) coherent intensity of oriented non-crystalline polyethylene tetrephthalate (PET) is determined by Symmetrical Transmission method; Besides, self-compiled WAXS Multi-peak Separation program 90 (MPS90) is used as well to separate the overlapped peaks at WAXS coherent intensity curves obtained at different azimuthal angles, thereof resulting in the two peaks caused by intermolecular atomic scattering, A(K=0.126) and B(K=0.169), and the other fives by intermolecular atomic scattering such as: C(K=0.304), D(K=0.553), E(K=0.374), F(K=0.465) and G(K=0.606)(K unit: nm-1), of which the origin of structure and the curves of primary peak parameters as a function of azimuthal angles are analysed in detail, thus obtaining the fine structural imformation from oriented non-crystalline PET.
