Reactive extrusion of polymers
WebReactive extrusion (REX) is based on the use of an extruder as a continuous chemical reactor to perform several standard processes in the polymer industry in a single step, including polymer synthesis and modification, as well as additivation, reinforcement and removal of volatile by-products.The result is a tailor-made material suitable for further … WebReactive compatibilization is the process of modifying a mixed immiscible blend of polymers to arrest phase separation and allow for the formation of a stable, long-term continuous phase. It is done via the addition of a reactive polymer, miscible with one blend component and reactive towards functional groups on the second component, which …
