| Abstract: | The radiation crosslinking of poly(L ‐lactide) (PLLA) was investigated using triallyl isocyanurate (TAIC) as a crosslinking agent. The gel fraction of crosslinked PLLA increased with TAIC concentration and γ‐ray dose. Crosslinking of PLLA started at low TAIC contents and low γ‐ray dosage. Differential scanning calorimetry and dynamic mechanical thermal analysis revealed that PLLA was completely crosslinked at high weight ratios and high γ‐ray doses. |
