Novel amphiphilic diblock copolymers by RAFT-polymerization, their self-organization and surfactant properties
… tool to synthesize novel well-defined amphiphilic diblock copolymers composed of the constant hydrophobic block poly(butyl acrylate) and of 6 different hydrophilic blocks with various polarities, namely a series of non-ionic, non-ionic comb-like, anionic and cationic hydrophilic blocks. …

Amphiphilic Diblock Copolymers: Study of Interpolyelectrolyte Complexation in Organic Media and Nanoencapsulation of Melatonin
… (PDMAEMAQ) and poly(acrylic acid) (PAA), and amphiphilic diblock copolymers based on polystyrene and the ionizable block poly(acrylic acid) were synthesized via Atom Transfer Radical Polymerization (ATRP). All polymers were characterized using 1H NMR and gel permeation chromatography to …

The synthesis of amphiphilic diblock copolymers: An investigation into the formation of micelles as a function of hydrophobic block length
<p>Acrylate-based amphiphilic diblock copolymers show great potential for anti-cancer drug transport due to their ability to aggregate into protective core-shell micelles. Using RAFT polymerization, copolymers containing poly(acrylic acid) and poly(methyl acrylate) blocks were made with high …

Novel functionalised biodegradable polymeric micro- and nano-structures for tissue engineering and drug delivery applications
… glycol)methacrylate)) (PLA-b-POEGMA) amphiphilic diblock copolymers were prepared using a one-pot simultaneous ROP and RAFT polymerisation method. A series of PLA-b-PMPC amphiphilic diblock copolymers are also prepared using a one-pot two-step ROP and RAFT polymerisation procedure. Two …

Synthesis and study of the micellization behavior of a dual temperature- and pH-responsive PAA-b-PNIPAM block copolymer
<p>Amphiphilic diblock copolymers are composed of hydrophilic and hydrophobic regions. When they are exposed to water, the hydrophobic blocks aggregate to form a hydrophobic core surrounded by hydrophilic regions outside to give a core-shell micelle. These micelles have many potential applications, …

Synthese und kolloidale Eigenschaften neuartiger Blockcopolymere mit beta-Dicarbonyl Einheiten = Synthesis and colloidal properties of a novel type of block copolymers bearing beta-dicarbonyl residues
… with the first synthesis and characterisation of amphiphilic diblock copolymers bearing b-dicarbonyl (acetoacetoxy) chelating residues. Polymers were obtained by Group Transfer Polymerisation (GTP)/acetoacetylation and controlled radical polymerisation techniques (RAFT).Different micellar …

Design and characterization of multicompartment micelles in aqueous solution
… studies were focused on the self-assembly of amphiphilic diblock copolymers in solution. The dissolution of these block copolymers in a solvent selective for one block results mostly in the formation of micelles. The micellar structure of diblock copolymers is inherently limited to a …

The multifarious self-assembly of triblock copolymers : from multi-responsive polymers and multi-compartment micelles
New ABC triblock copolymers were synthesized by controlled free-radical polymerization via Reversible Addition-Fragmentation chain Transfer (RAFT). Compared to amphiphilic diblock copolymers, the prepared materials formed more complex self-assembled structures in water due to three different …
