Antiviral Activity of Polyacrylic and Polymethacrylic Acids [PDF]

Journal of Virology, 1968
Polyacrylic acid (PAA) and polymethacrylic acid (PMAA) were investigated for their antiviral properties in tissue culture. Compared to other related polyanions, as dextran sulfate, polystyrene sulfonate, polyvinyl sulfate, and polyphloroglucinol phosphate, PAA and PMAA were found to be significantly more antivirally active and less cytotoxic.

Potentiometric titrations of polymethacrylic acid [PDF]

Journal of Polymer Science, 1947
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].

Composite Polymer-Clay Hydrogels Based on Bentonite Clay and Acrylates: Synthesis, Characterization and Swelling Capacity

Eurasian Chemico-Technological Journal, 2017
Clay minerals, especially montmorillonite, as well as bentonite minerals with a high content of montmorillonite, have the highest ability to adsorb various organic compounds. In the East Kazakhstan region, the Manyrak deposit has huge deposits of “pink”

Controlled radical fluorination of poly(meth)acrylic acids in aqueous solution

Nature Communications, 2017
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 ...

POLYMETHACRYLIC ACID: INDUCTION OF LYMPHOCYTOSIS AND TISSUE DISTRIBUTION

Cell Proliferation, 1975
AbstractPolymethacrylic acid (PMAA) induces up to a three‐fold increase in the lymphocyte population of peripheral blood in rats, goats and calves after intravenous administration. Other routes of administration are less effective. A maximum lymphocytosis is achieved after 3 hr with all doses in excess of 30 mg PMAA/kg body weight; over the next few ...

Study of immobilization of bolaform ions on polymethacrylic acid

BIO Web of Conferences
The study of the interactions of polyelectrolytes with organic ions, in particular bolaform ions, that is, having a mirror conformational chemical structural symmetry with respect to the centre of the molecule and exhibiting physiological activity, is particularly intriguing due to its potential for simulating biological processes and its implications ...
