Characterization of the synthesized polymers.
| Polymer | Structure according to 1H NMR (mol/mol/mol) |
LCST °C | Molecular weight (g/mol) using GPC | ||
|---|---|---|---|---|---|
| NIPAAm | HIPAAm | SAKIPAAm | |||
| P(NIPAAm-HIPAAm) | 96.4 | 3.6 | 0 | 37.4 | 1.904 × 104 |
| P(NIPAAm-co-HIPAAm-coSAKIPAAm) | 96.4 | 1.2 | 2.4 | 30.1 | 2.014 × 104 |
H NMR (Solvent: D2O, DMSO‑d6), GPC (Solvent:DMF, Standard: PSt), LCST was measured by Spectrophotometer (Solvent: PBS (pH = 7.5), Polymer conc.: 2.0 mg/mL, Heating rate: 0.2 °C/min, Wavelength: 450 nm).
