摘　　要：分析了不同条件下三线芳烃加压聚合产物（沥青）的结构特征，阐述了三线芳烃在加压炭化过程中可能发生的反应，并由此沥青调制出了高光学各向异性含量的可纺性中间相沥青。三线芳烃经过加压炭化，然后进一步热处理，这是一条制备中间相沥青碳纤维的可行途径。Abstract:In this paper,a heavy fraction of light diesel oil(LDOHF) was used as the feedstock to make mesophase pitch under pressure.The structural features of pyrolysis pitch derived from LDOHFand the possible react ions during pyrolysis were investigated.Ahigh anisotropic content spinnable mesophase pitch has been prepared.It is found that meso-pitch based carbon fiber can be made throughpyrolysis and further heat treatment of LDOHF.
