N-(p-乙烯氧基苯基)咔唑的合成和聚合

SYNTHESIS AND POLYMERIZATION OF N- (P-ETHENYLOXYPHENYL)CARBAZOLE

本文是含咔唑化合物及其聚合物系列研究的一部分,以对-溴苯酚为原料,经过乙烯基醚化,再同咔唑反应、合成了新的单体,N-(p-乙烯氧基苯基)咔唑(NEOPC),经过元素分析、NMR和IR等对NEOPC进行分析鉴定,研究了它的聚合行为。

N-(p-Ethenyloxyphenyl) carbazole (NEOPC) has been synthesized by etherification of p-bromophenol with vinyl acetate, then p-bromophenyl vinyl ether reacting with carbaxole in the presence of brass power and potassium carbonate at 200℃. The product was identified by elemental analysis, 1H NMR, 13C NMR and IR spectra. NEOPC is readily polymerized by conventional catalysts of cationic polymerization, such as BF3OEt2, I2, TiCl4, AlCl3, etc. But no polymer was obtained when free radical initiators were used. The rearrangement products and/ or the solvent-insoluble products in cationic polymerization of NEOPC. which may be produced by the crosslinking have been discussed.
