Analytical ultracentrifugation of latexes
Analytical Ultracentrifugation (AUC) is a fractionating technique based on the synchronized optical detection of the concentration profiles of the sample under a centrifugal acceleration of up to 300,000 g. The skilled choice of solvent, rotational speed and detection optics enables a variety of complementary AUC experiments due to the controlled interplay of centrifugal force, hydrodynamic fri...
متن کاملEffect of Copolymer Latexes on Physicomechanical Properties of Mortar Containing High Volume Fly Ash as a Replacement Material of Cement
This paper investigates the physicomechanical properties of mortar containing high volume of fly ash (FA) as partial replacement of cement in presence of copolymer latexes. Portland cement (PC) was partially replaced with 0, 10, 20, 30 50, and 60% FA. Copolymer latexes were used based on 2-hydroxyethyl acrylate (2-HEA) and 2-hydroxymethylacrylate (2-HEMA). Testing included workability, setting ...
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 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 کاملMicellization 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...
