Publikováno v: Polymer Science U.S.S.R.. 27:2699-2704
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. B
