Multicompartment Micelles by Aqueous Self-Assembly of μ-A(BC) _n Miktobrush Terpolymers.

ABSTRACT: The aqueous self-assembly of μ-A(BC) _n miktobrush terpolymers has been studied using dynamic light scattering and cryogenic transmission electron microscopy. In this system, the A block is hydrophilic poly(ethylene oxide), "O", the B block is hydrophobic poly(methylcaprolactone), "C", and the C block is hydrophobic and oleophobic poly(perfluoropropylene oxide), "F". Two terpolymers were examined: one with an average of about two C blocks and two F blocks and another with an average of about three C blocks and two F blocks. In both cases, the total molar mass is near 40 kg mol^-1, and the volume fraction of the single O block is greater than 50% of the whole. Both samples form multicompartment micelle structures with subdivided solvophobic cores of C and F
