Properties of PLA used in the experiment.
| Sr. No. | Material Name | Tg (°C) | Tm (°C) | Mw (kDa) | Mn (kDa) | PDI | Specific rotation [α] |
|---|---|---|---|---|---|---|---|
| 01 | PLLA (2003D) | 57 | 157 | 183 | 100 | 1.8 | −154° |
| 02 | PDLA | 57 | 178 | 224 | 122 | 1.8 | 156° |
| 03 | Oligomer (MCH) | — | — | ~3.0 | ~2.5 | 1.2 | — |
Tg and Tm were calculated using DSC second heating graph of specimen, the Mw, Mn and PDI were calculated using GPC compared with standard polystyrene standard, the specific rotation [α] of the sample were measure using polarimeter at 25 °C with 1.0 gm/100 mL concentration in chloroform.
