Lymphocytosis induced by polymethacrylic acid. Dose-effect and toxicity
Blut Zeitschrift für die Gesamte Blutforschung, 1975Intravenous polymethacrylic acid (PMAA) significantly increases the number of lymphocytes in the blood of the rat. The relationship between dose-effect and lymphocytosis is linear. The lethal dose in 30 days of PMAA is 120 mg/kg b.w. and the half-lethal dose 80 mg/kg b.w. The treatment with 40 mg/kg b.w.

Modification of track membranes with grafted polymethacrylic acid
Russian Journal of Applied Chemistry, 2014Track membranes modified by the irradiation-chemical method with polymethacrylic acid were studied. Grafted chains of polymethacrylic acid were impregnated with silver ions. The optimal parameters and conditions of the post-irradiation grafting of methacrylic acid were determined.

Potentiometric titration of polyacrylic acid, polymethacrylic acid and poly-l-glutamic acid
Polymer Science U.S.S.R., 1965Abstract Potentiometric titration is a sensitive method of investigating the structure of polyelectrolytes. Despite the fact that the course of the titration curves is determined both by the mutual positioning of the charge groups on the polymer chain, and also by the ionic environment, and also that the interpretation of the titration curves may ...

Negative Thixotropy of Aqueous Solutions of Polymethacrylic Acid
Nature, 1955SUFFICIENTLY concentrated aqueous solutions of polymethacrylic acid (about 8–15 per cent, depending on the degree of polymerization) form clear stiff gels at room temperature. At somewhat lower concentration, such systems are sols. On heating, these sols can be converted into gels; on cooling, the gelation is completely reversible, the gels reverting ...

The gelation of aqueous solutions of polymethacrylic acid☆
Polymer, 1962Abstract The dependence of rigidity and viscosity on concentration and temperature of aqueous solutions of polymethacrylic acid was measured in a specially designed viscoelastometer. The solutions show no rigidity up to a certain critical concentration range (depending on the degree of polymerization) of about one per cent in which the rigidity rises
