Abstract : Substituted phenyl-benzimidazo compounds are disclosed in which the phenyl group which is attached to the two position of the imidazo ring contains a carboxylic acid group, or derivatives thereof, para to the point of imidazo attachment. The benzimidozo is substituted in the 5,6 positions with amino groups or derivatives thereof. The compounds are particularly useful as AB-monomers in the preparation of poly ((2,6-imidazobenzimidazo) 1,4-phenylene). (Author)
