چکیده

Polymerization-induced formation of amphiphilic diblock copolymer vesicles is performed in water at high concentrations by a single-step nitroxide-mediated controlled free-radical emulsion polymerization of 4-vinylpyridine, initiated by a water-soluble poly(sodium acrylate) macroalkoxyamine at alkaline pH.

Invertible vesicles and micelles formed by dually-responsive diblock random copolymers in aqueous solutions.

Dually responsive diblock random copolymers poly(nPA0.8-co-DEAEMA0.2)-block-poly(nPA0.8-co-EA0.2) were made from N-n-propylacrylamide (nPA), 2-(diethylamino)ethyl methacrylate (DEAEMA) and N-ethylacrylamide (EA) via reversible addition-fragmentation chain transfer (RAFT) polymerization. Copolymers of different block length ratios, poly(nPA28-co-DEAEMA7)-block-poly(nPA29-co-EA7) (P1) and poly(nP...

Supramolecular self-assembly of nonlinear amphiphilic and double hydrophilic block copolymers in aqueous solutions.

Supramolecular self-assembly of block copolymers in aqueous solution has received ever-increasing interest over the past few decades due to diverse biological and technological applications in drug delivery, imaging, sensing and catalysis. In addition to relative block lengths, molecular weights and solution conditions, chain architectures of block copolymers can also dramatically affect their ...

Thermo-Induced Self-Assembly of Responsive Poly(DMAEMA-<italic>b</italic>-DEGMA) Block Copolymers into Multi- and Unilamellar Vesicles

A series of thermoresponsive diblock copolymers of poly[2-(dimethylamino)ethyl methacrylate-block-di(ethyleneglycol) methyl ether methacrylate], poly(DMAEMA-b-DEGMA), were synthesized by reversible addition−fragmentation chain transfer (RAFT) polymerizations. The series consist of diblock and quasi diblock copolymers. Sequential monomer addition was used for the quasi diblock copolymer synthesi...

Well-Defined Poly(oxazoline)-b-Poly(acrylate) Amphiphilic Copolymers: From Synthesis by Polymer-Polymer Coupling to Self-Organization in Water

In this contribution, we report on the self assembly in water of original amphiphilic poly(2-methyl-2oxazoline)-b-poly(tert-butyl acrylate) copolymers, synthesized by copper catalyzed azide-alkyne cycloaddition (CuAAC) reaction. For such purpose, polyoxazoline (poly(2-methyl-2-oxazoline)) and polyacrylate (poly(tert-butyl acrylate)) are first prepared by cationic ring-opening polymerization (CR...

Complex micelles from the self-assembly of coil-rod-coil amphiphilic triblock copolymers in selective solvents

We report an extensive simulation study on the spontaneous formation of complex micelles from coilrod-coil amphiphilic triblock copolymers in dilute solution resulting from solvent selectivity. The amphiphilic molecule is built from one hydrophilic block on each side and a hydrophobic block in the middle. The rigidity of the rod block is introduced by adding a bond-bending potential of the angl...
