Correction to “Stereocomplex Crystallization and Homocrystallization of Star-Shaped Four-Armed Stereo Diblock Poly(lactide)s with Different L‑Lactyl Unit Contents: Isothermal Crystallization from the Melt” Hideto Tsuji,* Nobutsugu Matsumura, and Yuki Arakawa J. Phys. Chem. B 2016, 120 (6), 1183−1193. DOI: 10.1021/acs.jpcb.5b11813 In Table 1, the coinitiator for 4-L8, 4-L11, 4-L14, and 4-L16 is pentaerythritol instead of L-lactic acid and the table caption was revised, as shown below. Table 1.
