Synthesis and characterization of poly(phenylene oxide) graft copolymers by atom transfer radical polymerizations

Synthesis, Structure, Hydrodynamics and Thermoresponsiveness of Graft Copolymer with Aromatic Polyester Backbone at Poly(2-isopropyl-2-oxazoline) Side Chains

“…One of the ways to synthesize graft copolymers is the so-called polymerization-polycondensation reaction, whereby polycondensation yields the main chain, followed by grafting from polymerization of side chains [ 17 , 18 , 19 , 20 ]. For such high molecular weight compounds, most solvents are selective.…”

Molecular Mobility of Molecular Brushes With a Polyimide Backbone and Polymethylmethacrylate Side Chains of Different Lengths

“…Polymer brushes are able to form various ordered nanostructures, and, owing to their special topology and side chains functionality, possess unique properties which are promising for applications in various fields as, e.g., highly active catalysts, sensors, nanoreactors, nanocontainers for targeted drug delivery, nanoporous membranes, etc. [1][2][3] Among a vast amount of synthesized polymer molecular brushes with various natures of the backbone and side chains, [4][5][6][7][8] those with strongly different thermodynamic properties of the backbone and side chains are of an especially great interest since they may form multiple nanostructures in selective solvents and films cast from such solvents. Recently, molecular brushes with rather high-molecular weight polyimide (PI) backbones and polyvinyl side chains were synthesized and possibilities of wide variations of the structure of side chains (including the introduction of functional groups into them), their length, and grafting density were demonstrated.…”

“…Temperature dependences of tg δ at 0.1 (1), 10 (2, 2 ), 1000 (3), and 100,000 Hz (4) for M3(1)(2)(3)(4) and PMMA(2 ).…”

A Reinforced Film of Graft Copolymers of Collagen and Acrylates

“…We produced a viscous solution of collagen by the alkaline treatment of animal hide with a solution of sodium hydroxide with subsequent neutralisation with acetic acid, removing the electrolytes by dialysis. The chemical modification of natural polymers is normally carried out by the graft copolymerisation of different monomers to macromolecules of the polymer [5][6][7][8]. Investigations were conducted into the production of graft copolymers of collagen with acrylic acid (AA) and methacrylic acid esters in the presence of potassium persulphate and azobisisobutyric acid dinitrile ester [9,10].…”
