Molecular weight on the maximum of the size exclusion chromatography (SEC) curve (Mp) vs. dose for the irradiated PCLs. The molecular weight corresponds to the whole sample at doses below gelation (below 100 kGy for PCL 80 K and below 150 kGy for PCL 50 K, PCL 43 K and PCL 32 K) and to the soluble part of the sample above gelation.
