Abstract
The present invention generally relates to pre-polymer and polymer compositions that can be photopolymerized. In one embodiment, the present invention relates to crosslinking agents that can be used in the photopolymerization of the pre-polymers and polymers disclosed herein. In another embodiment, the present invention relates to processes for producing pre-polymer, polymer and crosslinking compositions useful in photopolymerization reaction schemes. In one instance, the pre-polymers and polymers of the present invention can be crosslinked via a suitable crosslinking agent to produce networks (e.g., amphiphilic networks and/or co-networks).
