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.

Complex formation between polymethacrylic acid and polyacrylamide
Polymer Science U.S.S.R., 1982Abstract Complex formation between polymethacrylic acid and polyacrylamide in aqueous solutions has been investigated by IR-spectroscopy and elemental analysis, and by viscometry and potentiometric titration. It is shown that, in terms of units of the polymeric components, a complex product of equimolar composition is obtained.

Synthesis of graft copolymers of polycaproamide with polymethacrylic acid
Polymer Science U.S.S.R., 1987The modification of polycaproamide fibres by graft polymerization of methacrylic acid in the presence of the K2S2O8Na2S2O8 redox system and copper ions is studied. A connection is established between the amount of monomer sorbed on the polymer base and the kinetics of the graft polymerization reaction.

Potentiometric titration of a suspension of crosslinked polymethacrylic acid
Polymer Science U.S.S.R., 1977An aqueous suspension of a macro-mesh carboxylic cationite with particles of size ∼ 0·5 μ has been prepared from methacrylic acid and ethylene dimethacrylamide (2·5 mole %). The degree of dispersity was such that methods of polarized luminescence and potentiometric titration could be used for the investigation.

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 ...

Structure of graft copolymers of polycaproamide with polymethacrylic acid
Polymer Science U.S.S.R., 1990Abstract Electron microscopy and electron-probe microanalysis, contrasting and etching have been used to investigate the structure of graft copolymers of PA-6 with polymethacrylic acid obtained by chemically initiated liquid phase graft polymerization.
