Corrections to “Hydrolytically Stable and Thermo-Mechanically Tunable Poly(Urethane) Thermoset Networks that Selectively Degrade and Generate Reusable Molecules”

On page 22 410 of the original article, the reported units for cross-link density and the temperature used to calculate these values are incorrect. Specifically, the units reported for cross-link density in Table 2, paragraph three, and paragraph four should be mol/m³, not M/m³, and the reported temperature for calculating these values should be 80 °C, not 85 °C, as stated in paragraph four. The calculated cross-link density values in the third column of Table 2 and discussed within the article are correct. These corrections do not alter the conclusions of the work, although the units of M/m³ are incorrect and misleading to someone who is not familiar with calculating cross-link density values for polymeric networks.
