Phase diagram constructed for PLMAx–PBzMAy diblock copolymer nanoparticles prepared by RAFT dispersion polymerization of BzMA in n-dodecane at 20% w/w solids using AIBN at 70 °C (PLMA/AIBN molar ratio = 5.0). The post mortem diblock copolymer morphologies were determined by TEM. Note that higher order morphologies (worms and vesicles) can be obtained when using PLMA16 and PLMA18 macro-CTAs, but not when using the PLMA21 macro-CTA. TEM images (a), (b), and (c) correspond to examples of the three pure morphologies (spheres, worms, or vesicles), respectively, and the individual block copolymer compositions are indicated within the phase diagram.
