Water-soluble ABC triblock copolymers based on vinyl ethers: Synthesis by living cationic polymerization and solution characterization

Sequence control over thermo-triggered micellization and smart nanogels of copolymers based on PEGMA and aldehyde-functionalized monomer

“…[44][45][46] Contrary to the nucleation effect of PFPHPMA 6 blocks in P(FPHPMA 20 -ran-PEGMA 25 )-b-PFPHPMA 6 , PPEGMA 6 blocks of P(FPHPMA 26 -ran-PEGMA 20 )-b-PPEGMA 6 enhanced the hydration and sterically hindered aggregation, leading to the slow aggregation and predominantly in the insertion/expulsion mechanism of single chains. 47,48 The similar phenomena were also observed in ABC triblock copolymers separately by the groups of Armes [49][50][51] and Huang. 52,53 Their results demonstrated that altering ABC block copolymer sequence could effectively change the hydrophobicity thus micellization behaviors.…”

Diversity of Nanostructured Self-Assemblies from a pH-Responsive ABC Terpolymer in Aqueous Media

“…31 Although the observed partial clustering of micelles may introduce some error on the light scattering results (apparent N agg , R h ), direct observations by AFM and the topology of the terpolymer show that centrosymmetric core-shell-corona micelles seem to be formed at pH 1. Such micelles differ from those described in the literature, 32,33 which discusses micelles composed either from two highly incompatible hydrophobic compartments and a nonionic soluble corona 9,34 or those coreshell-corona structures with one hydrophobic core, positively charged shell (or thermo-sensitive shell 35 ), and neutral soluble corona. 7 In our case, the micelles are constituted of a hydrophobic core, a pH/thermosensitive hydrophilic inner compartment, and an outer positively charged soluble corona.…”

Vesicles with asymmetric membranes from amphiphilic ABC triblock copolymers

“…Different water-soluble polymers are inherently incompatible and undergo phase separation in aqueous media. Therefore, membranes formed by ABC triblock copolymers (with water soluble blocks A and C and a hydrophobic middle block B) should be asymmetric: one side predominantly covered by the blocks A and the other by the blocks C. Although the synthesis of ABC triblock copolymers of this type has been reported previously, 9 up to now there is no evidence for a membraneforming system.…”
