Short Description
Hyperbranched Polymers provides a comprehensive overview of the rapidly developing research in this area. Beginning with an introduction to the topic (including concepts, definitions and nomenclature, and descriptions of their structure and versatility), the book covers the synthesis of hyperbranched polymers, theoretical aspects and techniques of characterization, and information on their modification, supramolecular properties, and applications. Additionally, the book includes appendices, providing a list of known hyperbranched polymers as well as review articles published in this area.
The only comprehensive reference covering the properties, synthesis and applications of hyperbranched polymers.
* Helps the reader gain a better understanding of irregular branching and its relationship to a polymer's properties and potential applications, aiding in the design of highly functional materials.
* Covers the important theoretical aspects of the topic, as well as summarizing available techniques for characterizing these polymers.
* Compares hyperbranched polymers with conventional linear polymeric materials as well as perfectly branched dendrimers.
* Includes perspectives on future challenges in the synthesis and use of hyperbranched polymers in functional materials.
