ABSTRACT:
The present invention provides crosslinkable compositions useful in the preparation of hydrophilic gels, and are prepared from oligomers having pendent hydrophilic, poly(alkylene oxide) groups, pendent photoinitiator groups, and optionally polymerizable functional groups, and crosslinked by polyfunctional poly(alkylene oxides).
