The degree of methacrylate substitution according to methacrylic anhydride addition from 1H NMR analysis
| Gelatin | Methacrylic anhydride (ml) | Average methacrylation (%) a |
|---|---|---|
| 2 g (in 20 ml PBS) | 4 | 93 |
| 0.6 | 73 | |
| 0.1 | 45 | |
| 0.05 | 22 | |
| 0 | 0 |
Abbreviation: PBS, phosphate‐buffered saline.
The degree of methacrylate substitution for 1H NMR was determined by the formula: 1—(lysine integration signal of methacrylated‐substituted gelatin/lysine integration signal of unsubstituted gelatin). 31
