| Abstract:The synthesis of polymers with well-defined complex macromolecular architectures (wdCMA) is challenging for polymer chemists, important for physicists (structure/property relationships) and theoreticians (theory verification) and crucial for understanding the behavior of complex industrial polymers, such as low density polyethylene (LDPE). Several wdCMAs have been prepared over the last years using, mainly, living and controlled/living polymerization methodologies. Here, we present a new strategy based on 3-arm living stars (3-ALS) and anionic polymerization high vacuum techniques. The synthesis and characterization of selected wdCMAs (dendritic, single-star-comb, coil-b-double-miktoarm star-brush), among a plethora of structures, are discussed. Our methodology is a general one, and if applied to multiarm living stars, even more complex macromolecules, of both academic and industrial interest, can be achieved. |
