Synthetic hydrogels based on acrylic comonomers

Copolymer hydrogels on the base of acrylamide and acrylonitrile as well as acrylamide and acrylic acid were prepared using free-radical polymerization carried out in water medium at room temperature. It has been shown that depending on the monomers nature and ratio the swelling degree and the optical, deformational and diffusional properties of the obtained hydrogels can vary within wide limits
