含苯并噻唑环芳香族二腈的聚合物具有良好的热氧化稳定性,它远优于一般的耐高温高分子,而仅次于石墨,有关这方面的工作,我们已有报道.本文系报道这种聚合物的热裂解残余物的性能.所用的单体为2-(对氰基苯基)-6-氰基苯并噻唑(Ⅰ),聚合条件为:催化剂氯化锌用量为1％, Polymers containing benzothiazole ring aromatic dinitriles have good thermo-oxidative stability, which is much better than that of general high temperature resistant polymers and second only to graphite, and we have reported on this work. The properties of the pyrolyzed residue of this polymer are reported, using 2- (p-cyanophenyl) -6-cyanobenzothiazole (I) as monomer with a catalyst zinc chloride in an amount of 1 %,
