In order to see how the specific base-base interactions observed between complementary nucleic acid bases can be realized for free-radical polymerization systems, the template polymerization of methacrylate type monomers containing nucleic acid bases in the presence of template polymers containing complementary bases was studied. Stereoregular polymers were chosen as the template polymers. The radical copolymerization of the monomers containing complementary nucleic acid bases was also studied in different solvents.
