Abstract
The present invention describes a polymer and a precursor thereof; a prepolymer made essentially from a macromer that is cross-linked, for example, via its free hydroxy groups with a polyisocyanate, the macromer being made essentially from a polysiloxane and a polyol component; processes for the production of such prepolymers and polymers; the use of such polymers, for example, as artificial corneas, as molded articles, especially as contact lens material; also the use of a prepolymer or polymer for coating surfaces, especially functionalized polymer surfaces.
