Abstract
Polymers, co-polymers, and monomers using CO2 as a reagent and methods of production thereof are described. Polymerization methods include converting CO2 into a polymerizable monomer by exciting the CO2 with a light source. Such polymers and co-polymers can comprise two or more consecutive repeating units of Formula I:
