Abstract
Provided are novel reactive functionalized fumaric- and itaconic-containing prepolymers and compositions comprising the prepolymers used in the manufacture of medical devices. The prepolymers can be used to provide surface modified contact lenses formed from one or more fumaric- or itaconic-containing prepolymers having reactive functionality that is complimentary to reactive, hydrophilic polymers.
