SET-LRP of hydrophobic and hydrophilic acrylates in trifluoroethanol

Quantitative end-group functionalization of PNIPAM from aqueous SET-LRP via in situ reduction of Cu(ii) with NaBH4

“…[1][2][3][4][5][6][7][8][9][10][11] Control over the molecular weight distribution (MWD) and the rate of polymerization for SET-LRP is controlled through a selfregulated process 2, 12 driven by the disproportionation of Cu(I) to Cu(II) and Cu(0) in polar protic and aprotic solvents, water and their corresponding mixtures. Ligands stabilize the Cu(II) complex and further drive the equilibrium towards disproportionation.…”

Aqueous SET-LRP catalyzed with “in situ” generated Cu(0) demonstrates surface mediated activation and bimolecular termination

“…42 At the same time as these developments, the list of solvents used in SET-LRP was expanded to other solvents that in combination with aliphatic N-donor ligands, such as tris[(2-dimethylaminoethyl)] amine (Me 6 -TREN) 4,[43][44][45] and tris(2-amino)ethyl amine (TREN) 1,2,4,16,[43][44][45] mediate the disproportionation of Cu(I)X into Cu(II)X 2 and Cu(0). 46 This list includes but is not limited to H 2 O, 10,26,32,38,40,47 DMSO,6,7,12,21,23,40,[48][49][50][51] formamide (DMF), 46,47 dimethyl acetamide (DMAC), 46,47 alcohols, 22,48 fluorinated alcohols, [52][53][54] ethylene carbonate, 46,47 propylene carbonate, 46,47 and different mixtures of solvents with water, 46,47,55 mixtures of two solvents, 46,55 and even blood serum. …”

Synthesis of amphiphilic homopolymers with high chain end functionality by SET–LRP

“…Single electron transfer‐living radical polymerization (SET–LRP) has emerged as an excellent method for the synthesis of well‐defined polymers with quantitative or near quantitative functionality of their chain‐ends starting from hydrophilic, hydrophobic, and semifluorinated monomers . SET–LRP employs Cu(0) as catalyst, in the presence of an N‐containing ligand such as tris [(2‐dimethylaminoethyl)] amine (Me 6 ‐TREN) or tris (2‐amino)ethyl amine (TREN) for the activation of an alkyl halide initiator or dormant polymer chain end(s).…”
