Fecha de publicación: | 2010 | Editor: | Wiley-VCH | Citación: | Macromolecular Symposia 296(1): 303-310 (2010) | Resumen: | A new route to functional polymeric nanoparticles (PNPs) of different chemical nature in the 3 to 20 nm size range is reported by combining both radical addition fragmentation chain transfer (RAFT) polymerization and “click” chemistry (CC) techniques. RAFT polymerization was employed for the synthesis of well-defined statistical copolymers with pending –Cl groups along the macromolecular chain. After transformation of the –Cl groups to –N3 groups by treatment with sodium azide, an appropriate bifunctional cross-linker is employed to obtain PNPs under CC conditions promoting intramolecular cycloaddition (cross-linking). Following this new route, polystyrene, poly(alkyl (meth)acrylate), polymethacrylic acid, poly(sodium styrenesulfonate) and poly(N-isopropyl) NPs have been synthesized and in-deep characterized. | Descripción: | Trabajo presentado al Modern Trends in Polymer Science (EPF'09) celebrado en Graz (Austria) del 12 al 17 de Julio de 2009. | Versión del editor: | http://dx.doi.org/10.1002/masy.201051042 | URI: | http://hdl.handle.net/10261/108729 | DOI: | 10.1002/masy.201051042 | ISSN: | 1022-1360 | E-ISSN: | 1521-3900 |
