Abstract

See full text

A water-insoluble hydrophilic gel comprising: (A) about 30 to about 90% of a hydrophilic (a) polymer of identical or different watersoluble mono-olefinic monomers, or (b) copolymer of said watersoluble monomers with 1 to 70% of water-insoluble, identical or different mono-olefinic monomers, which polymer or copolymer is cross-linked with (B) about 10 to about 70% of a terminal diolefinic hydrophobic macromer having a molecular weight from about 400 to about 8000.
