Marques, Dina S.; Gil, Maria H.; Baptista, Cristina M. S. G.
Influence of the isomeric structures of butyl acrylate on its single-electron t...
Coelho, Jorge F. J.; Carvalho, Erica Y.; Marques, Dina S.; Popov, Anatoliy V.; Percec, Virgil; Gil, M. H.The aim of this work is to the study the influence of the isomer structures of butyl acrylate monomer on the single-electron transfer/degenerative chain transfer mediated living radical polymerization (SET-DTLRP). The kinetic of isobutyl acrylate is determined for the first time by SET-DTLRP in water catalyzed by sodium dithionite. The plots of number-average molecular weight versus conversion and ln([M]0/[M]) ...
Synthesis of poly(ethyl acrylate) by single electron transfer-degenerative chai...
Coelho, Jorge F. J.; Carvalho, Erica Y.; Marques, Dina S.; Popov, Anatoliy V.; Percec, Virgil; Gonçalves, Pedro M. F. O.; Gil, M. H.Living radical polymerization of ethyl acrylate was achieved by single-electron-transfer/degenerative-chain transfer mediated living radical polymerization in water catalyzed by sodium dithionite. The plots of number-average molecular weight versus conversion and ln[M]0/[M] versus time are linear, indicating a controlled polymerization. This method leads to the preparation of alpha,omega-di(iodo)poly(ethyl acry...
Synthesis of Poly(lauryl acrylate) by Single-Electron Transfer/Degenerative Cha...
Coelho, Jorge F. J.; Carvalho, Erica Y.; Marques, Dina S.; Popov, Anatoliy V.; Goncalves, Pedro M.; Gil, Maria H.Living radical polymerization of lauryl acrylate was achieved by SET/DTLRP in water catalyzed by sodium dithionite. The work describes the synthesis of a highly hydrophobic and polar monomer in aqueous medium. The plots of versus conversion and ln[M]0/[M] versus time are linear, indicating a controlled polymerization. This method leads to alpha,omega-diiodopoly(lauryl acrylate)s that can be further functionaliz...
