Applications of Telechelic Reversible Addition Fragmentation Chain Transfer Polymers

Controlled radical polymerization by carboxyl‐ and hydroxyl‐terminated dithiocarbamates and xanthates

“…However, they can be condensed with a functionalized block followed by radical polymerization of vinyl monomers. For example, 4l was condensed with a polyurethane end‐capped with diisocyanate groups, and this was followed by radical polymerization with acrylates to make a polyurethane–polyacrylate block copolymer 35, 36. According to Scheme , 2 and 3 can form an ester with hydroxyl‐terminated block(s), and this is followed by radical polymerization.…”

Living Radical Polymerization by the RAFT Process - A Second Update

“…Reviews on specific areas include the kinetics and mechanism of RAFT polymerization, [15][16][17][18] the use of RAFT to probe the kinetics of radical polymerization, [19,20] the use of RAFT in organic synthesis, [21] amphiphilic block copolymer synthesis, [22,23] the synthesis of end functional polymers, [24] the synthesis of star polymers and other complex architectures, [25,26] the use of trithiocarbonate RAFT agents, [27] the use of xanthate RAFT agents (MADIX), [28] polymerization in heterogeneous media, [29][30][31][32] RAFT polymerization initiated with ionizing radiation, [33] polymer synthesis in aqueous solution, [34][35][36][37] surface and particle modification, [38,39] synthesis of self assembling and/or stimuli responsive polymers, [36,40] RAFT-synthesized polymers in drug delivery, [22,41] and other applications of RAFTsynthesized polymers. [30,42,43] The process is also given substantial coverage in most recent reviews that, in part, relate to polymer synthesis, living or controlled polymerization, or novel architectures. Some of these documents are referred to in subsequent sections of this review.…”

“…The use of the corresponding trithiocarbonates 118-125 has also been promoted in this context. [27] Secondary aromatic dithioesters with R = -CHPh(CN) (42) and -CHPh(CO 2 R) (43)(44)(45)(46)(47)(48) and analogous trithiocarbonates 144, 145, and 146-148, respectively, have been shown to have utility in controlling 'R'-connected 79* [227] S S S S NIPAM [240] S S S S 80* [86,241,242] BMA [243] DMAEMA [240][241][242][243] AA [241] BA [243] St [241,243] DMAEMA-b-BMA [243] DMAEMA-b-BA [243] DMAEMA-b-St [243] St-b-HEMA/DMAEMA [86] 81 [244] CN S S…”
