Nováková, Pavlína ; Petruš, Josef (referee) ; Kučera, František (advisor)
The bachelor thesis deals with the preparation and properties of copolymer acrylamide gels. The theoretical part is focused on the general characteristics of gels, closer look at copolymeric acrylamide gels – preparation methods, various possibilities of initiation, crosslinking, and use of comonomers. Factors influencing swelling of the gel were described. The experimental level focuses on the preparation of neutral polyacrylamide gel and acrylamide copolymeric gel with anionic component, sodium acrylate. First, the formation of the copolymer and the presence of functional groups were verified by infrared spectroscopy with Fourier transformation. Then gels of different concentrations of sodium acrylate and the crosslinking agent, bisacrylamide, were prepared by radical solution polymerisation. The influence of the gel composition on the swelling degree in distilled water was investigated on the prepared samples. The selected samples were then swelled in environments of different pH and ionic strengths to assess the influence of the external environment on the swelling degree.
