Characteristics of polyurethane micelles.
| Polymer | Micelle diameter (nm) | PDI | CMC (mg/L) |
|---|---|---|---|
| SS-PU-SS-PEG | 115.1 ± 7.3 | 0.251 | 10.2 |
| SS-PU-b-PEG | 156.4 ± 18.2 | 0.163 | 1.83 |
PDI = polydispersity index; CMC = critical micelle concentration; SS-PU-SS-PEG = PEG-sheddable reduction-sensitive polyurethane; SS-PU-b-PEG = PEG-unsheddable reduction-sensitive polyurethane.
