1. A hydrophilic, crosslinkable oligomer composition comprising a) a first component oligomer comprising a plurality of polymerized monomer units having pendent, free-radically polymerizable functional groups, and a plurality of polymerized monomer units having pendent, hydrophilic poly(alkylene oxide) groups;
- and (b) a second component oligomer comprising a plurality of polymerized monomer units having pendent, free-radically polymerizable functional groups.

Abstract
Hydrophilic compositions are described, which are prepared from a first oligomer containing pendent polymerizable groups and pendent hydrophilic groups, crosslinked with a co-reactive second component oligomer possessing polymerizable groups. The compositions may be used as in preparation of hydrophilic gel coatings or layers for medical devices.
