摘要：

Temperature-dependent small-angle X-ray scattering from polyethylene is analyzed using a correlation function technique. It is found that the correlation function gives two maxima corresponding to long periods fo 163 A and 205 A at room temperature. These must correspond to different morphological structures. These long periods remain almost constant up to the crystallization temperatures and after that they merge into a single long period which increases with increasing temperature.
