Methacrylic acid, abbreviated MAA, is an organic compound. This colorless, viscous liquid is a carboxylic acid with an acrid unpleasant odor. It is soluble in warm water and miscible with most organic solvents. Methacrylic acid is produced industrially on a large scale as a precursor to its esters, especially methyl methacrylate (MMA), and to poly(methyl methacrylate) (PMMA). WebAnionic polymers: Anionic polymethacrylate polymers contain methacrylic acid functional groups, which dissociate and render the polymer soluble at the higher pH of the small …

WebBoth poly (acrylic and methacrylic acids) form mole-to-mole complexes with polyethylene glycols in aqueous media. In one extensive series of studies, the end groups of the glycols were esterified with 1-pyrenebutyric acid to render the glycol fluorescent. A difference was found in the behavior of the two acids. WebApr 23, 2024 · Carbohydrate and saccharide sensing in water remains very challenging. Using the covalent reversible interaction between boronic acids and the diol groups in carbohydrates is still one of the most common approaches. However, the binding affinity and solubility of isolated boronic acids are poor in water, which significantly limits their …
