Resumen: © 2018 The Royal Society of Chemistry. The high bromine chain end functionality of polyacrylates synthesized by single electron transfer living radical polymerization (SET-LRP) mediated by TREN in a biphasic acetone-water mixture containing Cu(ii)Br2 can be exploited to introduce specific functional groups to the chain-ends of these polymers. Here, the α-bromoester end groups of poly(methyl acrylate) (PMA) synthesized in this biphasic SET-LRP system using non-activated Cu(0) wire as catalyst were reacted also under heterogeneous biphasic conditions with potassium acrylate to yield PMA macromonomers and telechelics with α- and α,ω-acrylate chain ends. The reagents used in both steps are air insensitive and inexpensive. 500 MHz 1H NMR, GPC and MALDI-TOF analyses in combination with the thio-bromo click reaction were used to confirm the high efficiency of this two-step protocol. The reactive nature of these macromonomers by the preparation of a PMA-g-PMA more complex architecture was also demonstrated.
