摘要
用元素分析、ＩＲ、Ｘ射线衍射、ＥＳＲ、１３ＣＮＭＲ 等分析方法研究聚丙烯腈（ＰＡＮ）在不同温度下裂解产物的结构特点．结果表明：ＰＡＮ热裂解产物最终具有共轭不饱和多环芳烃的结构．
The structural features of pyrolytic products of polyacrylonitrile(PAN) at different pyrolytic temperatures have been studied by elemental analysis, IR, X\|ray diffraction, ESR, 13 C NMR. The results show the pyrolytic products of PAN finally have unsaturated ladder\|shaped structure of conjugated poly\|cyclic aromatics.
