a
Calculated from the feed molar ratio of DIB to PVP segments or PS–PVP BCPs.
b
Actual CLDs are determined from fitting XPS data.
c
The uncertainly is expressed as one standard deviation.
d
Results acquired from DLS in a methanol/THF (v:v = 3:1) mixture at C = .25 mg/ml. The DLS data is presented as mean ± standard deviation (n = 3).
