摘要
用元素分析、ＩＲ、Ｘ—射线衍射、ＥＳＲ、１３Ｃ－ＮＭＲ等分析方法研究了聚丙烯腈（ＰＡＮ）在不同热裂解温度下产物的结构特点．结果表明，ＰＡＮ热裂解产物最终具有共轭不饱和多环芳烃的梯状结构．
The structural features of pyrolytic products of polyacrylonitrile (PAN) at different pyrolytic temperatures have been studied by elemental analysis, IR, x-ray diffraction, ESR, C-NMR analytic methods. The results show the pyrolytic products of PAN finally have unsaturated ladder-shaped structure of conjugated poly-cylic aromatics.
