Hyperbranched Aromatic Polyesters and Their Application in Blends of Linear Polyamides
In the last two decades, hyperbranched (hb) polymers have drawn much attention and obtained intensive research activities both from industry and academia. They are known to have unique and interesting properties which derive from their three dimensional structure and the large number of functional g...

In the last two decades, hyperbranched (hb) polymers have drawn much attention and obtained intensive research activities both from industry and academia.

Furthermore, the easy synthetic accessibility of hb polymers by one-pot synthesis is advantageous as well and allows easy scale-up of laboratory reactions. Having the characteristics as mentioned above, hb polymers are considered good candidates for blend components or melt processing modifiers. In fact, hb polymers have already been used as blend components or additives aiming for different effects.
