结晶度是表征聚合物性质的重要参数,它对聚合物的物理和机械性能有很大影响,在测定聚合物的结晶度的各种方法中,X-射线衍射法的意义明确且应用最为广泛。然而,用X-射线衍射法测定聚合物结晶度绝大部分只限于单组份体系,用于共混体系的报道尚不
Crystallinity is an important parameter characterizing the properties of polymers. It has a great influence on the physical and mechanical properties of polymers. In various methods for determining the crystallinity of polymers, X-ray diffraction has a clear meaning and is widely used . However, the determination of the crystallinity of a polymer by X-ray diffraction is mostly limited to one-component systems, and reports for blending systems are not yet available
