Abstract: A polyimide composition includes 1 to 99 weight percent, preferably 70 to 99 weight percent, more preferably 75 to 95 weight percent of a first polyimide; and 1 to 99 weight percent, preferably 1 to 30 weight percent, more preferably 2 to 25 weight percent of a second polyimide, wherein the first polyimide and the second polyimide are different, and wherein the polyimide composition has a melt flow rate that is greater than a melt flow rate of the first polyimide and less than a melt flow rate of the second polyimide; an apparent viscosity that is less than an apparent viscosity of the first polyimide and less than an apparent viscosity of the second polyimide; and a notched Izod impact strength that is greater than a notched Izod impact strength of the first polyimide and greater than a notched Izod impact strength of the second polyimide.

Abstract: Provided herein are methods for preparing dynamic cross-linked polymer compositions derived from an ester oligomer component, a chain extender component, and one or more of a transesterification or poly condensation catalyst are described. The dynamic cross-linked polymer compositions may be prepared via melt poly condensation.

Abstract: Methods for measuring certain properties of a crosslinked polycarbonate are disclosed. The storage modulus of a crosslinked polycarbonate is measured over a specified temperature range, and the average magnitude of the storage modulus over that temperature range is obtained. The average magnitude can be correlated to both crosslinking within the polycarbonate, and to the flame performance of the crosslinked polycarbonate.
