Journal ArticleDOI
Ultrafast synthesis of ultrahigh molar mass polymers by metal-catalyzed living radical polymerization of acrylates, methacrylates, and vinyl chloride mediated by SET at 25 degrees C.

TL;DR: It is reported that polarsolvents such as H(2)O, alcohols, dipolar aprotic solvents, ethylene and propylene carbonate, and ionic liquids instantaneously disproportionate Cu(I)X into Cu(0) and Cu(II)X(2), facilitating an ultrafast LRP in which the free radicals are generated by the nascent and extremely reactive Cu( 0) atomic species.
Journal ArticleDOI
Mechanism of Carbon−Halogen Bond Reductive Cleavage in Activated Alkyl Halide Initiators Relevant to Living Radical Polymerization: Theoretical and Experimental Study
Abdirisak Ahmed Isse,Armando Gennaro,Ching Yeh Lin,Jennifer L. Hodgson,Michelle L. Coote,Tamaz Guliashvili +5 more
TL;DR: It is presented that injection of one electron into RX produces only a weakly associated charge-induced donor-acceptor type radical anion complex without any significant covalent σ type bond character between carbon-centered radical and associated anion leaving group.
Journal ArticleDOI
Kinetic simulation of single electron transfer–living radical polymerization of methyl acrylate at 25 °C
TL;DR: In this article, a mechanistic comparison of the ATRP and SET-LRP is presented, and it is shown that the activation of the initiator and of the propagating dormant species is faster than of the homolytic inner-sphere electron-transfer process responsible for ATRP.
Journal ArticleDOI
A comparative computational study of the homolytic and heterolytic bond dissociation energies involved in the activation step of ATRP and SET‐LRP of vinyl monomers
Tamaz Guliashvili,Virgil Percec +1 more
TL;DR: In this article, a quantum-chemical calculation of the homolytic and heterolytic bond dissociation energies of the model compounds of the monomer and dimer is reported.
Journal ArticleDOI
Inorganic Sulfites: Efficient Reducing Agents and Supplemental Activators for Atom Transfer Radical Polymerization
Carlos M. R. Abreu,Patrícia V. Mendonça,Arménio C. Serra,Anatoliy V. Popov,Krzysztof Matyjaszewski,Tamaz Guliashvili,Jorge F. J. Coelho +6 more
TL;DR: Inorganic sulfites such as sodium bisulfite (NaHSO3) have been studied as reducing agents for atom transfer radical polymerization (ATRP), and they act not only as very efficient reducing agents but also as supplemental activators for SARA (supplemental activator and reducing agent) at ambient temperature.
