Radiation synthesis of linear and crosslinked poly [2-(methacryloyloxy)ethyl]trimethylammonium chloride and complex formation with potassium hexacyanoferrates (II, III) in aqueous solutions

Linear and crosslinked poly[2-(methacryloyloxy)ethyl]trimethylammonium chloride was synthesized by γ-irradiation polymerization in aqueous solutions. Interactions between linear poly[2-(methacryloyloxy)ethyl]trimethylammonium chloride and low molecular coordination compounds K 3 [Fe(CN) 6 ] and K 4 [Fe(CN) 6 ] have been studied in aqueous solutions by viscometric and turbidimetric measurements. The formation of complexes with certain stoichiometry depending on the nature of the low molecular ion was detected. Hydrogels of poly[2-(methacryloyloxy)ethyl]trimethylammonium chloride absorb these salts and undergo contraction. The stability of the complexes formed in different ionic strength media has been evaluated.
