General chemical composition of multiblock copolymers used in this study. In blue shading: amorphous, hydrophilic block, n: PCL, x: PEG. In green shading: urethane linker, in red shading: semicrystalline block, m: poly(l-lactic acid). The two polymers used in this study differ in their block weight fraction (hydrophilic block–semicrystalline block), PEG chain length, and total PEG weight fraction.
