Abstract
A water-insoluble hydrophilic gel comprising (A) about 20 to about 90% by weight of a hydrophilic (a) polymer of identical or different water-soluble monoolefinic monomers, or (b) copolymer of said water-soluble monomers with 1 to 80% (of total monomers) of water-insoluble, identical or different monoolefinic monomers; which polymer or copolymer is cross-linked with (B) about 10 to about 80% by weight of a terminal polyolefinic siloxane macromer having a molecular weight from about 400 to about 8500.
