Terpolymers are used to generate bio-decomposable self-assemblies. PEG-PVL-PGMA terpolymers synthesized via a combination of organocatalyzed living radical polymerization (RCMP) with polymerization-induced self-assembly (PISA), generating vesicle, multicompartment micelle (MCM), and core-compartmentalized worm (CCW), where PEG, PVL, PGMA poly(ethylene glycol) monomethyl ether, poly(?-valerolact...
