The alterations in weight averaged molecular mass (Mw) were also assessed, providing insights into the overall polymer chain dynamics. Across the PBS-DLS copolymers, the changes in Mw generally fell within a range from 4 to 13%, indicative of moderate modifications in the polymer structure. However, a notable exception was observed in the PBS-DLS-PEG 60-35-05 formulation, where a significant reduction of 45%
