  摘要：

  基于五环核心系统的刚性含氟化合物、单体和聚合物，例如在12,14位置带有全氟烷基和/或芳基的12H,14H-5,7-二氧代五环并芴，以及在5,12位置带有全氟烷基和/或芳基的5H,12H-7,14-二氧代五环并芴。这些单体在制备先进高性能聚合物，特别是聚酰亚胺时具有实用性。刚性五环核心降低了聚合物的热膨胀系数，而氟代取代基改善了介电常数和吸水性能。每个单体单元在其五环核心内含有两个-O-桥和两个--CRR.sub.f桥（其中R是芳基、取代芳基或全氟烷基，R.sub.f是全氟烷基）。

  Rigid fluorine-containing compounds, monomers, and polymers based on pentacyclic core systems, such as 12H,14H-5,7-dioxapentacene of formula (I) with perfluoroalkyl and/or aryl groups in the 12, 14 positions, and 5H,12H-7,14-dioxapentacene, of formula (II) with perfluoroalkyl and/or aryl groups in the 5,12 positions. These monomers have utility in the preparation of advanced high-performance polymers, particularly polyimides. The rigid pentacyclic core decreases the coefficient of thermal expansion of the polymers, while the fluorinated substituents improve the dielectric constant and water absorption properties. Each monomer unit contains within its pentacyclic core two-O-bridges, and two -CRRf bridges (where R is aryl, substituted aryl or perfluoroalkyl, and Rf is perfluoroalkyl).

  The present invention relates to a method for preparing wholly aromatic polyimide powder with antistatic properties or electric conductivity. In particular, the present invention relates to a method for preparing wholly aromatic polyimide composite powder, comprising the steps of dissolving aromatic diamine in a phenolic polar organic solvent in which electrically conductive carbon black powder and multi-wall carbon nano-tube (MWCNT) powder are dispersed, adding aromatic tetracarboxylic dianhydride thereto, and polymerizing the resulting mixture. The wholly aromatic polyimide powder prepared according to the method of the present invention shows excellent antistatic properties or electric conductivity simultaneously with maintaining similar or equal heat-resistance and mechanical properties as compared to conventional polyimide resin.
