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.
