Characterization of mPEG-b-CMP copolymers.
| Sample | mPEG/eHSPMC (feed ratio) | Compositiona (ratio) | Yield (%) | M w b (Da) | M w/Mnb | CACc (mg L−1) | Sized (nm) | PdId |
|---|---|---|---|---|---|---|---|---|
| mPEG-b-CMP15 | 1 : 12 | 1 : 15 | 73 | 4693 | 1.77 | 26.67 | 102.0 ± 0.9 | 0.27 ± 0.009 |
| mPEG-b-CMP30 | 1 : 25 | 1 : 30 | 84 | 5135 | 1.83 | 9.40 | 140.1 ± 0.5 | 0.22 ± 0.003 |
| mPEG-b-CMP45 | 1 : 35 | 1 : 45 | 82 | 5895 | 1.58 | 4.63 | 150.8 ± 1.2 | 0.18 ± 0.004 |
a
Determined by 1H NMR.
b
The molecular weight and Mw/Mn were determined by GPC against PS standards.
c
Calculated by fluorescence measurements using Nile Red as probe.
d
Measured by DLS.
e
HSPMC represents monomer 3-((3-hydroxypropyl)selanyl)propyl methyl carbonate.
