Anticorrosion activities of polymethacrylic acid and grafted/modified polymethacrylic acid on pure aluminium in acid medium

Materials Today: Proceedings, 2021
Abstract Polymethacrylic acid (PMAA) and modified Polymethacrylic acid functionalized with catechol (PMAA/CAT), hydroquinone (PMAA/HQ) and catechol-hydroquinone (PMAA/CAT-HQ) were synthesized by oxidative decarboxylation method using ammonium persulphate as an oxidant and characterized using UV–Visible spectroscopy, FT-IR, XRD, TGA and SEM studies ...

Thermal degradation of polymethacrylic acid

Journal of Polymer Science Part A: Polymer Chemistry, 1992
AbstractThe thermal degradation of polymethacrylic acid was found to have two separate decomposition regions. The first decomposition region, due to anhydride formation primarily, was caused by the conversion of polymethacrylic acid to polymethacrylic anhydride.

The sedimentation and diffusion of sodium polymethacrylate and polymethacrylic acid

Journal of Polymer Science, 1954
AbstractThe sedimentation constants and diffusion coefficients of sodium polymethacrylate and of polymethacrylic acid have been determined at various concentrations of polymer and of added electrolyte and the nature of the charge effects is considered. A ratio y = (molarity of added electrolyte)/(grundmolarity of polymer) is used to obtain S20 at y = ∞

Potentiometric behavior of polymethacrylic acid

Journal of Polymer Science Part A: General Papers, 1964
AbstractThe potentiometric behavior of polymethacrylic acid is discussed in terms of a conformational transition. A thermodynamic treatment of this transition is presented. The titration curve of polymethacrylic acid is analyzed in a detailed way and quantitative information regarding the transition is obtained.

Precipitation of trypsin with polymethacrylic acid

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1970
It has been shown that the precipitation of trypsin with polymethacrylic acid results in a reversible or irreversible (after an incubation period) formation of a complex and, in the latter case, a stable, nonactive addition product can be isolated.

The thermal decomposition of polymethacrylic acid

Polymer, 1960
Abstract When polymethacrylic acid decomposes thermally at 200°C two separate reactions occur. The minor one is depolymerization which results in small yields of monomer. The major reaction is anhydride formation by elimination of water between pairs of carboxyl groups.
