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。
WAXD method showed that the crystallinity of PP / EPO blends decreased with the increase of EPO content, and the unit cell parameters had no relation with the composition ratio. The second type of lattice distortion was calculated. According to the PP / EPO DSC and twist braiding experiments, the PP / EPO blends were incompatible under all compositions. However, the amorphous region may be partially compatible.
