The m/n ratio represents the hydrophilic/hydrophobic balance of the block copolymer, which means the ratio of degree of polymerization for each block. In their research reported on page 1500, Shohei Kozuka, Keita Kuroda, Kazuhiko Ishihara, and Shin‐ichi Yusa prepared amphiphilic diblock copolymers with m/n ratios of 12, 1.8, and 0.3 and studied their association behaviors in water. The diblock copolymers have pendant phosphorylcholine and tris(trimethylsiloxy)silyl groups. These polymers take an interpolymer aggregation state with various morphologies. The m/n ratios of 12, 1.8, and 0.3 yielded spherical shapes, cylindrical micelles, and vesicle interpolymer aggregate shapes, respectively. (DOI: 10.1002/pola.29407 )
