Cross-linking density of P:P and P:P:Bs grafts using the swelling method.
| Vascular grafts | Swelling percentage (%) | n (mol/m3, χ = 0.48) |
|---|---|---|
| P:P | 702.2 ± 32.4 | 31.1 ± 4.3 |
| P:P:B0 | 533.3 ± 25.6 | 71.1 ± 5.2 |
| P:P:B1 | 466.7 ± 17.5 | 94.2 ± 6.1 |
| P:P:B2 | 422.2 ± 28.2 | 115.7 ± 8.5 |
| P:P:B3 | 391.1 ± 15.8 | 130.3 ± 7.9 |
n – Cross-linking density. χ – Flory-Huggins polymer-solvent interaction parameter.
