Figure 2.

(a) Phase diagram constructed for (1:9 PGalSMA₃₄ + PGMA₅₁)-PHPMA_x diblock copolymer nano-objects prepared by RAFT aqueous dispersion polymerization at 70 °C. The target PHPMA DP and the total solids content were systematically varied and the post mortem copolymer morphologies obtained at >98% HPMA conversion were determined by TEM. N.B. S, SW, W, V, and FS denote spheres, short worm-like micelles, worm-like micelles, vesicles, and frustrated (i.e., kinetically trapped) spheres, respectively. (b) Representative TEM images obtained for (1:9 PGalSMA₃₄ + PGMA₅₁)-PHPMA_x copolymer nano-objects prepared by RAFT aqueous dispersion polymerization of HPMA at 70 °C. The targeted DP (x) for the PHPMA block (herein denoted by ‘H’ for brevity) and the copolymer solids content % is indicated on each image.
