Poly(lactic acid) (PLA) was hybridised with epoxide-functionalised silane (GTMS) through reactive extrusion. The GTMS was grafted successfully to PLA via a ring-opening reaction with the nucleophilic end groups of PLA. For hybridisation, PLA was extruded with various amounts of GTMS between 0 and 2....
