(A) Reaction scheme for the postpolymerization modification of P(LA-co-BiBOEA) prepolymers with HOBiB to obtain P(LABiB-co-BiBOEA) macroinitiators. (B) ¹H NMR spectra of P(LA-co-BiBOEA) (top) and P(LABiB-co-BiBOEA) (bottom) recorded in acetone-d₆. (C) Overlaid SEC traces of P(LA-co-BiBOEA)₁₄₀ and P(LABiB-co-BiBOEA)₁₄₀, showing an increase in molecular weight following postpolymerization modification. (D) SEC traces corresponding to P(LABiB-co-BiBOEA) macroinitiators of varying DP (140, 220, 430).
