Acetylated and succinoylated inulin were synthesized by reacting inulin with acetic anhydride and succinic anhydride. The modified inulin was characterized by FTIR, NMR, and potentiometric titration. The compositional dependence of their properties, such as solubility, pKa, and melting point, was in
## Abstract **Summary:** Diblock and multiblock copolymers composed of a poly(D,Lβlactide) (PLA) or poly(trimethylene carbonate) (PTMC) core with a hydrophilic chain of poly(ethylene glycol) (PEG) were prepared. These copolymers, in which the core is connected to PEG through a polyfunctional molecu
