An atom-efficient, wholly aqueous one-pot synthesis of zwitterionic diblock copolymers has been devised. Such copolymers can serve as highly effective aqueous dispersants for nano-sized transparent yellow iron oxide particles.
A block copolymer library of polylactide and poly(2-hydroxyethyl acrylate) was prepared via sequential ring opening polymerization and RAFT polymerization in a one-pot approach.
The combination of ROP and ATRP in a one-pot process with DBU as ATRP ligand and ROP catalyst results in the synthesis of poly(l-lactide)-b-poly(methyl methacrylate) block copolymers.
