Effect of external factors on the swelling of hydrogels based on poly(ethylene glycol) maleate with some vinyl monomers

Abstract

Effect of the pH of the medium, temperature, and nature of solvents and inorganic salt on the behavior of hydrogels based on copolymers of poly(ethylene glycol) maleate with acrylic and methacrylic acids and acrylamide was studied. It was shown experimentally that the susceptibility of the hydrogels to changes in the factors mentioned above, depending on the nature of a comonomer.
