This study evaluates hydrogels based on 2‐hydroxyethyl methacrylate (HEMA) and diethylene glycol ester of methacrylic acid (DEGMA) as candidates for a suitable matrix for immobilizing marine bacteria. Results are presented of investigations of the effect of monomer structure and polymer composition on wettability and mechanical properties. We also studied the effect of composition on heat produced during polymerization, an important factor affecting bacterial viability during the process of immobilization. Hydrogels based on DEGMA in artificial sea water solution demonstrate the attractive combination of good mechanical properties and high water content. At low concentrations of monomer, little heat is produced during polymerization. These properties make DEGMA‐based hydrogels suitable for immobilizing marine bacteria.
