Abstract
Miscibility in systems containing poly-2,2( m-phenylene)5,5' -bibenzimidazole (PBI) and a variety of aromatic polyimides (Pl) has recently been reported.^(1-3) To study the intermolecular interac­tions in these blends, mixtures of benzimidazole (BI) and other similar aromatic compounds with PI in the polyamicacid (PAA) form have been prepared. In the context of these experiments a catalytic activity of Bl on the imidization reaction (which transforms a PAA to the corresponding Pl) was observed. Such catalytic activity is also reported in a recent patent.
In the present study, the imidization reactions of three PAAs have been followed in the presence of different aromatic compounds by infrared (IR) measurements.
