摘要
The invention relates to the use of a polymer network comprising a poly(meth) acrylate which is linked by means of oligomer chains which contain chemically bound ethylene oxide units as hydratable groups, the ethylene oxide units being present in the form of oligomer blocks containing 5/14 200 ethylene oxide units, for coating and/or impregnating a substrate or for manufacturing products such as eye lenses and matrices for immobilizing and/or the regulated release of active substances. The polymer network has improved mechanical properties and a desirable permeability to water or water vapour.
