The amphiphilic block copolymers of 2-(dimethylamino)ethyl methacrylate and methyl methacrylate: Synthesis by atom transfer radical polymerization and solution properties

Synthesis of block copolymer-stabilized Au–Ag alloy nanoparticles and fabrication of poly(methyl methacrylate)/Au–Ag nanocomposite film

“…The amphiphilic block copolymer, [poly(2-(N ,N -dimethylamino)ethyl methacrylate)]-b-poly(methyl methacrylate)-b-[poly(2-(N ,N -dimethylamino)ethyl methacrylate)] (PDMAb-PMMA-b-PDMA) of molecular weight 45,000 and a polydispersity index 1.20 was synthesized using same procedure as reported earlier using Atom Transfer Radical Polymerization (ATRP) [32]. Briefly, a difunctional Br-PMMA-Br was prepared at 35 • C using CuBr/o-phen as the catalyst and 1,2-bis(bromoisobutyryloxy)ethane as the initiator with the following recipe: MMA (4.7 g, 47 mmol), EtOH (4.2 ml), H 2 O (0.8 ml), CuBr (134.9 mg, 0.94 mmol), o-phen (372.3 mg, 1.88 mmol) and 1,2-bis(bromoisobutyryloxy)ethane (340 mg, 0.94 mmol).…”

Synthesis of Three Types of Amphiphilic Poly(ethylene glycol)‐block‐Poly(sebacic anhydride) Copolymers and Studies of their Micellar Solutions

“…Copolymer micellar solutions were obtained by three different methods: (1) directly dissolving the copolymers in water; (2) an oil-in-water (O/W) emulsion/solvent evaporation method; and (3) a precipitation/solvent evaporation method. Method 1: 20.0 mg of copolymer sample was added to 10 mL of distilled water.…”

“…[1][2][3][4] They can form micellar structures with a hydrophobic inner core and hydrophilic outer shell in aqueous media. [5] The polymeric micelles have unique characteristics, such as nanosize, and good thermodynamic stability in physiological conditions.…”

Well-defined novel fluorene-containing polymers: Synthesis, fluorescent properties, and micellar nanoparticles

“…Furthermore, it has been studied in such applications as flocculation agents [19], biocides [20] and in gene delivery systems [21]. Its amphiphilic block copolymers have application potential in the stabilization of latex particles, emulsions, dispersions, separations and drug and gene delivery vehicles [22]. Several flexible methods including atom transfer radical polymerization (ATRP) [22], oxyanion-initiated polymerization [23], and reversible addition-fragmentation chain (RAFT) polymerization [24] provide feasible syntheses of amphiphilic block copolymers.…”
