Abstract

A study has been made of features of complexation of polyamic acids with aprotonic solvents. It is shown that a polyamic acid film is a solid solvocomplex with an aprotonic solvent that contains two solvent molecules per repeat-unit of the polymer. By changing the chemical nature of the solvent included in the solvocomplex one can control the formation of supermolecular structure in nonoriented polyamic acid films.
