摘　　要：WAXD方法测定表明PP/EPO共混体系的结晶度随EPO组份含量的增加而降低,晶胞参数与组份比无关,并计算了第二类晶格畸变。根据PP/EPO的DSC和扭辫实验得出在所有组成下PP/EPO共混体系是不相容的。但在非晶区可能部分相容。The crystal structure and miscibility of PP/EPO biends have been investigated byWAXD, TBA and DSC. The degree of crystallinity of PP/EPO blends decreases with increa-sing content of EPO,and the unit cell parameters are independent of the blend composition.Hosemann′s treatment was used to separate crystallite size and distortion broadening. TheX-ray diffraction profile was corrected by Cauchy and Gaussian functions. Observationsmade with TBA and DSC indicated that, though immiscibility of PP/EPO blends, thereis a partial interfacial miscibility between the two amorphous phases.
