摘要
用密度法和X射线衍射法测定了加入成核剂的聚丙烯材料的结晶度。结果表明,2种方法测定结果虽然存在较大差异,但所测得的结晶度随成核剂加入量的变化具有相同的变化规律。
The crystallinity of polypropylene (PP)filled with nucleating agents (0.1% - 2.0%) was measured by density method and X - ray diffraction intensity method, respectively. The results indicated that there existed a marked difference in the crystallinity analyzed by the two methods, but the variation of the crystallinity with the added quantity of the nucleating agent reflected the similar trend.
