Acidic hydrolysis cleaves the hexahydro-triazine group into
three parts as shown by Zhu and coworkers.

cedure as reported by Pradipta et al. the cores of the star poly-
mers were hydrolyzed, using hydrochloric acid in methanol or
ethanol.
The resulting cleavage of the three aminal groups in
the hexahydro triazine core leads to three linear PEG or PPO Macromol. Rapid Commun. 2019, 1900020 Scheme 1. Synthesis strategy for
