Analysis of PEG-poly(PDL-co-DO) diblock copolymers
| Polymer | PDL/DO/PEG2K (feed molar ratio) | Polymer yield a | PDL/DO unit ratio (mol/mol) | PEG Content (wt%) | Mw (Da) b | Mw/Mn b |
|---|---|---|---|---|---|---|
| P56D44 | 40:60:4.2 | 71% | 56:44 | 40% | 12300 | 1.7 |
| P65D35 | 50:50:4.6 | 72% | 65:35 | 38% | 13400 | 1.8 |
| P71D29 | 60:40:5.0 | 77% | 71:29 | 36% | 15100 | 1.8 |
Calculated based on total monomer substrate weight.
Measured by GPC using polystyrene standards.
