Solvent Minimized Synthesis of Amides by Reactive Extrusion [PDF]
Angewandte Chemie International EditionAbstractHerein, we report on the translation of a small scale ball‐milled amidation protocol into a large scale continuous reactive extrusion process. Critical components to the successful translation were: a) understanding how the different operating parameters of a twin‐screw extruder should be harnessed to control prolonged continuous operation, and

Preparation of Biodegradable Materials by Reactive Extrusion [PDF]
Materials Science Forum, 2008 This work aimed to prepare biodegradable polymeric materials based on blends of a synthetic high density polyethylene (HDPE) and biodegradable polymers such as polylactic acid (PCL) and poly(caprolactone) (PLA), in a co-rotating twin-screw extruder. A polyethylene modified with maleic anhydride was used as compatibiliser.
