Table 2
Percent decrease in tensile strength of PP/PCCS after biodegradation.
| Starch contents (Wt.%) | % loss in tensile strength after 30 days | % loss in tensile strength after 60 days | % loss in tensile strength after 90 days |
| 0 | 0.66 | 1.44 | 2.05 | 10 | 5.80 | 9.42 | 21.16 | 20 | 6.44 | 11.95 | 18.67 | 30 | 7.77 | 13.64 | 22.08 | 40 | 9.01 | 8.87 | 18.26 | 50 | 11.69 | 17.84 | 20.23 |
