    摘要: Novel aromatic AB2 imide monomer with thermally reactive trialkylsiloxy and aryl fluoride moieties, which can be polymerized to form hyperbranched aromatic polyimides in the presence of a metal fluoride catalyst. Nanoclay composites were generated by either (i) direct blending of a preformed hyperbranched aromatic polyimide and Closite nanoclay (≦20 wt %) or (ii) blending of the AB2 monomer, CsF catalyst and Closite nanoclay (≦20 wt %) followed by thermal solid-state polymerization of the AB2 monomer homogeneously dispersed in the nanoclay.
