    In this study, we blended PCL into poly(lactic acid) (PLA) and compatibilized these PLA/PCL blends by\nelectron-beam irradiation in the presence of a reactive agent to overcome drawbacks of PLA. To produce compatibilized blends,\nmixtures of the PLA/PCL/reactive agent were prepared using a twin-screw extruder and exposed to electron-beam radiation at room\ntemperature. Glycidyl methacrylate (GMA) was chosen as the reactive agent to achieve interfacial cross-copolymerization between\nPLA and PCL phases. Morphological, rheological, and mechanical properties and biodegradabilities of blends were investigated. The\nmorphological study showed significantly improved interfacial adhesion for compatibilized blends, and this was supported by FTIR\nanalysis and a rheological study. Impact strengths, thermal stabilities, and rheological properties of PLA/PCL blends were improved\nby compatibilization, and the biodegradabilities of compatibilized PLA/PCL blends were greater than that of pure PLA.
