We chose to modify the anhydride monomers with photopolymerizable methacrylate functionalities. Methacrylate-based polymers have a long history in biomedical applications, ranging from photocured dental composites [20] to thermally cured bone cements [21]. Furthermore, photopolymerizations provide many advantages for material handling and processing, including spatial and temporal control of the polymerization and rapid rates at ambient temperatures. Liquid or putty-like monomer/initiator... 

Other Monomer Systems. The above sections are by no means an exhaustive list of monomers that are used in free radical photopolymerizations. Diallyldiglycolcarbonate (18) has been used for many years in optical components such as lenses (51). Acrylamide (19) is used in stereolithography and to prepare holographic materials (52-54). A(-vinylpyrrolidinone (20) is copolymerized with acrylates and methacrylates for cosmetic and biomedical applications (55). Norbornene (21) is copolymerized with thiols for optical fiber coatings (56). Liquid crystal polymers (22) based on acrylates and thiol-enes are being developed to produce mirror coatings, polarizing films, and liqiud crystal displays (57,58).
