There are two fundamental reasons for the drop in the cyclization rate constant of solid polyamic acids: the change in amic acid group reactivity as a result of decreasing molecular mobility when the imide ring content increases, and the existence of various kinetically nonequivalent states of amic acid groups and the statistical distribution of these groups over these states (6, 7).
