Representative TEM images obtained for PDMA94–PBzMAx diblock copolymer nanoparticles prepared at 25% w/w solids via RAFT dispersion polymerization in ethanol at 70 °C. Increasing the target degree of polymerization, x, of the core-forming PBzMA block results in progressively larger spherical nanoparticles. (a) PDMA94–PBzMA100 (b) PDMA94–PBzMA300 (c) PDMA94–PBzMA495 and (d) PDMA94–PBzMA810.
