ABC triblock polymethacrylates: Group transfer polymerization synthesis of the ABC, ACB, and BAC topological isomers and solution characterization

Multi‐Compartment Unimolecular Micelles from (ABC)n Multi‐Arm Star Triblock Terpolymers

“…Thus, the block sequence in linear triblock terpolymers is an important structure determining factor for their aggregation in aqueous solution. [15,38] Star terpolymers exhibited reasonably similar SLS M w values in water and THF, implying a lack of aggregation in water. The lack of aggregation in these three star terpolymers was not surprising given that their number of arms was much greater than the aggregation numbers in water of the corresponding linear triblock terpolymers.…”

“…The solution properties of ABC triblock terpolymers have recently attracted much attention because of the novel nanostructured self-assemblies formed in selective media. [13][14][15][16][17][18][19][20][21][22][23][24][25] Particular emphasis has been given to the so-called multi-compartment micelles [26,27] comprising more than two hydrophobic non-centrosymmetric compartments [28][29][30][31] or core-shell-corona centrosymmetric structures. [32][33][34][35] The present work aims to combine the linear ABC triblock terpolymer structure with the star architecture (Scheme 1).…”

Double-Hydrophilic Block Copolymers: Synthesis and Application as Novel Surfactants and Crystal Growth Modifiers

“…[50] Trimethylsilyl groups were also not suitable as trimethylsilyl methacrylate polymerized very slowly, thus leading to low molar mass products only. [48] Various other AB diblock copolymers of DMAEMA and MAA were synthesized in quantitative conversion and with good polydispersities (M -w /M -n = 1.10-1.14) [51] by GTP as already described. [49] DMAEMA could also be copolymerized with 2-(N,Ndiethylamino)ethyl methacrylate (DEAEMA) to yield DHBCs, which are homogeneously soluble at pH 2 only due to protonation of the tertiary amine residues.…”

Design and synthesis of a two compartment micellar system based on the self-association behavior of poly(N-acylethyleneimine) end-capped with a fluorocarbon and a hydrocarbon chain

“…These techniques complement each other by probing the cmc, the hydrocarbon and the fluorocarbon aggregation, respectively. In contrast to the high numbers of studies on solution properties of AB block copolymers only a few studies have dealt with the aggregation behavior of ABC triblock copolymers [15][16][17][18][19] . In our approach to the preparation of systems with two different micellar domains we focused on the synthesis of a polymeric surfactant by a living cationic polymerization mechanism composed of a hydrophilic polymer block that is end-tagged with a hydrocarbon moiety at one end and a fluorocarbon one at the other end, both of defined length.…”
