Laser Raman Spectra of Polymethacrylic Acid [PDF]
Laser-excited Raman spectra are reported for polymethacrylic acid as a solid, an aqueous gel, and a strongly alkaline aqueous gel. The spectrum of the neutral gel is identical with that of the solid, although alkalization produces some changes. The spectra are analyzed in terms of changes in chain configuration.

Potentiometric titrations of polymethacrylic acid [PDF]
AbstractPotentiometric titrations of polymethacrylic acid were performed at different concentrations, different molecular weights, and in the presence of neutral salts, as well as in dioxane‐water mixtures. It was shown that the pH of the solutions fulfills the relation, pH = pK — n log [(1 — α)/α].

Controlled radical fluorination of poly(meth)acrylic acids in aqueous solution
Fluorinated alkenes have very poor reactivity in copolymerizations with non-fluorinated polar monomers. Here the authors show silver-catalyzed decarboxylative radical fluorination of poly(acrylic acid) with Selectfluor in water at room temperature to ...
