Micellization of casein-graft-dextran copolymer prepared through Maillard reaction.
Casein is almost insoluble at around pH 4.6, which is its isoelectric point (pI). Grafting copolymer, casein-g-dextran, was prepared through the Amadori rearrangement of the Maillard reaction. The copolymer has a reversible pH sensitive property: micellization at the pI of casein forming a casein core and dextran shell structure and dissociation when pH differs from the pI. The micelles produce...
متن کاملConstruction and micellization of a noncovalent double hydrophilic block copolymer.
The first noncovalent double hydrophilic block copolymer was constructed through inclusion complexation between beta-cyclodextrin and the adamantyl group; it can further self-assemble into two distinctly different micelles in response to pH and temperature in dilute aqueous solution.
متن کاملPreparation and Application of Dimer Acid/lignin Graft Copolymer
Dimer acid (DA) was grafted onto lignin (EHL) to form a graft copolymer DA-g-EHL. The selection of the reaction type and the optimization of the reaction conditions for the grafting reaction were conducted through orthogonal and single factor experiments. FT-IR and thermal analysis were used to characterize the graft product. It was found that, compared with free radical grafting, DA can be gra...
متن کاملAnalysis of the Complexation/Decomplexation Phenomena in Graft Copolymer Networks
Graft copolymer networks of poly(methacrylic acid-g-ethylene glycol) exhibiting pHdependent swelling behavior due to the formation of interpolymer complexes were prepared by free radical solution polymerization of methacrylic acid and poly(ethylene glycol) monomethacrylate. Dynamic swelling studies established the swelling/deswelling process due to hydrogen bonding. Additionally, the effects of...
متن کاملCerie-Initiated Polymerization onto Polyaerylonitrile with Carbohydrate End Groups. Graft versus Block Copolymer Formation
Starch-g-polyacrylonitrile (starch-g-PAN) copolymers were prepared by ceric ammonium nitrate initiation, and the major portion of the starch in these graft copolymers was then removed by acid hydrolysis to yield PAN with oligosaccharide end groups. Although these PAN-oligosaccharide samples reacted with methyl methacrylate in the presence of eerie ammonium nitrate, the resulting products were l...
