AbstractThere is disclosed a hydrophilic gel suitable for exposure to repeated long-term contact with live tissues or mucous membranes and consisting of macromolecules obtained by polymerizing a mixture of at least two copolymerizable units and a crosslinking agent. The mixture consists of from 52 to 99.5 parts by weight of N,N-diethylacrylamide, 43 to 0.1 parts by weight of a member selected from the group consisting of N,N-dialkyl acrylamide, N-alkyl methacrylamide, nitriles of acrylic and methacrylic acids and from 5 to 0.4 parts by of a divinylic monomer selected from the group consisting of diesters of acrylic acid and methacrylic acid, and methylene or ethylene-bis-methacrylamide or acrylamide.
