Polymethacrylates containing 6-cyanouracil

Polymethacrylates containing 6-cyanouracil or 5-bromouracil units in the side chain of the polymer had the highest photosensitivity. However, since these polymers were tacky in nature, a copolymer of butadiene and the methacrylate monomer with pendant 6-cyanouracil was synthesized. This polymer showed resolution down to 1 p m (Figure 12).
