| Résumé : |
Hyperbranched polymers are a new class of polymeric material belonging to the group of macromolecules with highly branched structures and a large number of end groups. The structure of these polymers has a great impact on their physical and chemical properties. Many commercially-available chemicals can be used as the monomers in these systems, which should extend the availability and accessibility of hyperbranched polymers with various new end groups, architectures and properties. Because of their unique behaviour, hyperbranched polymers are suitable for a wide range of applications, especially for coatings. This paper provides a concise review on molecular architecture and a general outline of methods to synthesise hyperbranched polymers and summarises their physico-chemical properties. The hyperbranched concept is discussed in terms of preparative methods, applications and advantages with respect to polymers for coatings. Hyperbranched polyesters, alkyds, epoxies, polyacrylates and siloxanes are discussed. Examples for other polymers such as polyurea, polyurethane dispersions (PUDs) and polyamides are also given. |
