in Mw was recorded. This pronounced reduction could be attributed to a more extensive breakdown of polymer chains during enzymatic degradation. In examination of the NMR data, the anticipated PEG content in our samples was theoretically set at 5 wt.% for both segmental ratios. However, a more detailed analysis revealed a calculated incorporation of 7 wt.% PEG in the sample with a 70 wt.% hard segment and 10 wt.% PEG in the sample with a 60% hard segment. Thus, much higher amount of PEG in the latter system likewise contributed to notable decrease in Mw, as already discussed. The observed changes are in good agreement with the changes of surface morphology, as it will be further discussed in the subsequent SEM section, exploring the correlation between these molecular and morphological changes.
