Polymerization of acrylamide by electrolytically generated Ce(IV)‐organic acid redox systems

Abstract

Ce(IV) salt‐malonic acid or citric acid initiator systems were used for the polymerization of acrylamide in the presence of electrolysis. This allowed Ce(III) to be converted to Ce(IV) during polymerization. Graphite, silver, chromium/nickel, lead, platinum and stainless‐steel electrodes were used. The highest polymerization yield was obtained with a stainless‐steel electrode.

Complexation of uranyl ion by three polyacrylamide type polymers: Electrochemical preparation and leaching tests investigations

“…They were used without any additional treatment. The polymerization initiators were supplied by Aldrich: ammonium cerium(IV) nitrate (21,, citric acid (24,062-1), malonic acid (M129-6), ammonium persulfate: (NH4)2S208 (21,558-9), 4,4'-azobis-(-4-cyanovaleric acid), ACVA (11, and tetramethylethylenediamine:…”

Electroinduced dispersion polymerization of acrylonitrile in the presence of poly(acrylic acid) and catalytic amount of CE(IV)

“…12 Under electrolytic conditions and by electrogeneration of metal ion, using Ce(IV)-carboxylic acid, KMnO 4 -carboxylic acid, or Ce(IV)-EDTA redox systems, water-soluble polyacrylamides containing the carboxylic acid end group were synthesized recently in our laboratory. [13][14][15] Recently, polymerization of acrylamide was investigated in an aqueous solution in the presence of a Ce(IV) salt-oxalic acid initiator system in an electrochemical cell with and without separation of the anolyte and the catholyte with the purpose of better understanding the electrochemically induced redox mechanism of acrylamide and to obtain a high yield of the polymer at low initiator concentrations. 16 The same idea was applied to the polymerization of N-vinylcarbazole (NVCz) in an anodic compartment in the presence of a catalytic amount of a ceric salt as an oxidant during the electrochemical polymerization of NVCz in a divided electrochemical cell.…”

Radical polymerization of acrylamide initiated by ceric ammonium nitrate-methionine redox initiator system

“…Then the calculated amount of Ce(IV) salt aminocarboxylic acids. [2][3][4][5][6][7][8] The aim of this work solution was added dropwise with stirring over was to investigate the effect of reaction conditions 5 min. After a chosen polymerization time, the [the concentration of Ce(IV), polymerization reaction mixture was left standing for 1 h. Polytime, and temperature] on molecular weight, acrylamide was isolated by pouring the reaction yield, and molecular weight distribution (MWD) mixture into acetone, filtering, and drying in air.…”
