A novel oganogel has been prepared from PLLA/PDLA stereocomplex by electron beam (EB) irradiation in the presence of triallyl isocyanurate (TAIC). The maximum crosslinking density was obtained at radiation dose of 30 kGy. The crosslinked samples revealed improved thermal and mechanical properties. Further characterization studies showed that the sample with the best thermal stability and rather good mechanical properties was obtained through irradiation followed by annealing. Biodegradability was also investigated by alkaline and enzymatic degradations. Although biodegradation of the initial PLLA/PDLA stereocomplex was delayed by crosslinking network, the crosslinked samples were significantly degraded by alkaline and proteinase K.
