A study was conducted to produce two distinctly different polymers having specific backbone structures and side chain functionalities through direct, selective, and orthogonal polymerizations of a single bifunctional monomer. A single bifunctional monomer bearing the controlled radical polymerization (CRP) and ring-opening (metathesis) polymerization (RO)(M)P) was designed for the study to allow CRP or ROMP to be performed. Conditions were optimized to achieve selective atom transfer radical polymerization (ATRP) and ROMP of 5-norborene-2-methylene methacrylate, a single bifunctional monomer, and a norbornenyl (Nb) unit. The radical polymerization of the methacrylate headgroup was investigated in the presence of norbornenyl group. 1H NMR spectroscopy was also used to determine the monomer conversion and number-averaged molecular weights (Mn).
