Dendritic macromolecules tailoring properties

Dendritic macromolecules exhibit compact globular structures which lead to their low viscosity in the melt or in solution. Furthermore, dendritic macromolecules are characterized by a very large number of available functional groups, which lead to unprecedented freedom for changing/tuning/tailoring the properties of these multivalent scaffolds via complete or partial derivatization with other chemical moieties. All these features have contributed to multidisciplinary applications of these unique macromolecular structures in recent years 6, 7). The development of efficient synthetic routes in recent years has given rise to a virtually unlimited supply of commercially available dendritic polymers, at very affordable price. The transport properties of hyperbranched and dendritic polymers have recently attracted attention as potentially new barrier and membrane materials 8-9). [Pg.46]

The dendritic polymer literature reviewed herein provides compelling evidence that these materials are a unique and versatile class of branched polymers. The synthesis of dendritic macromolecules can be accomplished by numerous methods allowing for specific tailoring of the characteristics of the polymer, to yield desired properties or functionality. While some of the procedures reported are quite intricate, requiring multiple cycles of synthetic steps and work-up, one-pot syntheses have also been developed for hyperbranched and dendrigraft polymers, making these materials more viable for (large-scale) commercial production and industrial applications. [Pg.581]

In conclusion, phosphorus-containing dendrimers and dendrons offer a large palette of properties usable in various areas of materials chemistry. Indeed, we have demonstrated that these dendritic macromolecules allow the tailored modification of various siufaces by covalent or ionic interactions. Furthermore, these dendritic macromolecules can be also incorporated within new materials, the dendrimer acting as a template for the formation of the material. [Pg.151]
