Efficient synthesis of sterically-stabilized nano-objects via RAFT dispersion polymerization of benzyl methacrylate in alcoholic media.

摘要: Synthesis of diblock copolymer nano-objects: alcohol is a good idea! RAFT dispersion polymerization benzyl methacrylate in using weak polyelectrolyte-based chain transfer agents allows the facile synthesis sterically stabilized nano-objects with very high monomer conversions. Such syntheses are usually problematic when conducted water due to electrostatic repulsion between highly charged stabilizer chains, which impedes situ self-assembly. Construction detailed phase diagram facilitates reproducible well-defined spheres, worms or vesicles, since it mixed regions be avoided. Aqueous electrophoresis studies confirm that these can acquire substantial surface charge transferred aqueous solution ionization (or protonation) polyacid polybase) chains.
