Abstract

A novel tertiary amine and amino acid‐based “schizophrenic” pH‐responsive block copolymer, PDEA‐b‐PAP, has been synthesized by RAFT polymerization. By directly dissolving this copolymer in acid or basic aqueous solution block copolymer vesicles with switchable coronas and membranes were prepared. These novel assemblies were characterized using TEM, DLS, zeta potential, and SLS analysis.

Two micellar states are possible for a novel PPO-PDEA diblock copolymer synthesized by atom-transfer radical polymerization. Subtle variation of the solution pH value and temperature is all that is needed to form both conventional micelles (with the PDEA block in the core) and reverse micelles (with
