摘要
本实验根据X射线衍射强度理论和聚合物两相模型概念,采用逐级近似的方法,利用X射线衍射技术,测得了固相氯化法CPR的结晶度。结果表明,当Cl%≤12.0%时,随着氯含量的增加,固相氯化法CPE的结晶度逐渐减小。
In this paper the crystallinity in the chlorinated polyethylene (CPE) from solid-phase chlor-ination was determined by the method of x-ray successive approximation after the correctionsfor absorption, atomic scattering, temperature, Lorentz and polarization factors. The results showthat the crystallinity in the CPE is decreased with increase of chlorine content when the chlorinecontent is less than or equal to 12.0%.
