Hydrogels belong to the group of materials that are highly popular on the polymer market. Therefore many studies are currently carried out on the mentioned group of polymers using different modifying agents as well as different research techniques. In the research, synthesis of hydrogel polymers based on acrylic and modified with agar was conducted using UV radiation. Syntheses were performed using different amount of cross linking agent as well as a solution of agar with different concentrations do check an impact of both variables on physicochemical properties of attained materials. Next, sorption capacity and surface morphology of prepared hydrogels were determined. Furthermore, behavior of the tested materials in Simulated Body Fluid (SBF) was defined in view point of the potential use of the proposed polymers for biomedical purposes. Based on the conducted analyses it can be stated that obtained hydrogels were characterized by relatively high sorption capacity that depended largely on the amount of cross linker used during the synthesis as well as on the amount of the additive present in hydrogel matrix. Furthermore, tested polymers were characterized by a relatively corrugated surface. Additionally, analyzed materials exhibited biocompatibility in relation to simulated body fluid. Therefore it can be noticed that hydrogels based on acrylic acid and modified with agar solution can be considered as materials that can be used for biomedical applications.
