## Abstract Multinuclear aromatic compounds are distinguished by considerable thermostability. In a number of cases they have been shown to be endowed with semiconductor properties. In view of this the development of a method of synthesis and investigation of aromatic polymers with a common system
Anhydride terminated polyamic acid prepolymer was prepared from pyromellitic dianhydride and a diamine (para-phenylene diamine/benzidine) in dimethyl formamide. The prepolymer was reacted with the other diamine to obtain (A,B),.,, block copolymic acid. The polyamic acid was converted to the polyimid
