Correction to “Synthesis, Morphology, and Particle Size Control of Acidic Aqueous Polyurethane Dispersions”

Abstract

The originally published Table 2 is incorrect. The sample names were entered in the wrong order such that they matched up with the incorrect corresponding parameters. This mistake has been resolved in the corrected Table 2 below: R is the geometric mean particle radius with multiplicative standard deviation σ*. The proportion of PU distributed as supramolecular structures is quantified by ϕ₂/ϕ_tot. R_g gives the radius of gyration of these structures, and ν is a structural parameter that indicates solubilization of these polymer-like structures. The caption to the originally published Figure 7 refers to the tables incorrectly. The first reference should be made to Table 1 and not to Table S1. The second reference should be made to Table 2 and not to Table 1. The value ϕ₂/ϕ_tot is given in Table 2, as specified in the corrected caption below: Corrected Figure 7 caption: Relationship between the acid (COOH) content in the original PU formulation (Table 1) and the fraction of PU in supramolecular structures formed by (H₁₂MDI)_n+1DMPA_n molecules, measured by SAXS (Table 2, ϕ₂/ϕ_tot) for PUD samples synthesized with polyether (soft segment) of M_n = 650 g mol^–1 (blue circles), 1000 g mol^–1 (green squares), and 2000 g mol^–1 (red triangles).
