Engineering Polymer Alloys by Reactive Extrusion

摘要

During the last fifty years blending of dissimilar polymers has been a major path to tailor materials with new properties in industry. Since most of the interesting polymer blends are immiscible, the different compatibilisation strategies have received a lot of attention. In the area of engineering plastics, reactive blending is usually used to compatibilise immiscible polymers. The most important polymer alloys prepared by reactive extrusion [Polycarbo-nate/Polybutyleneterephthalate-alloys (PC/PBT), Polyamide/Polyphenylene-ether-alloys (PA/PPE), Styrenics/Polyamide-alloys (ABS/PA)] have already reached an interesting sales volume. The commercial success of these materials is mainly related to their unique combinations of properties, which enables their use in a multitude of applications.
