It was observed that the crystallinity of VDC AN copolymer with high VDC content is linear function of its AN mass content, while that with high AN level is function of three order of AN mass content from the DSC and X ray diffraction study.

• 由 DSC法和 X射线衍射法得到高 VDC含量的共聚物结晶度与 AN含量成线性关系 ,而在高 AN含量时则与 AN组成成三次多项式关系
