STUDY ON X-RAY DIFFRACTION OF CHLORINATED POLYETHYLENE(CPE) FROM SOLID-PHASE CHLORINATION
Abstract:
In this paper polyethylene(PE) and chlorinated polyethylene(CPE) from solid-phase chlorination were studied by the variance method in x-ray diffractometer.After the deduc-tion of back ground and the corrections for Kαdoublet and the broadening of the instrument, the crystallite sizes and degrees of lattice distortion in PE and CPE were obtained.The results show that(1) With the aid of microcomputer,the method of variance-range function can be used for determining the crystallite size and degree of lattice distortion in poly-mer;(2) In CPE the crystallite size decreases and the degree of lattice distortion increases with increase of chlorine content when the later is≤12.0% in the polymer.
