The polymerization that IUPAC terms reversible‐deactivation radical polymerization is a controlled radical polymerization technique (CRP) that allows producing polymers with tailored properties without the stringent conditions typical in ionic polymerization. A theoretical analysis is presented of the influence of operating and design conditions on the product properties for the nitroxide‐mediated copolymerization (NMP) of styrene and α‐methyl styrene. Several reactor configurations are analyzed, with different feeding policies and temperature profiles. To this end a mathematical model is developed to predict copolymer average properties and the complete bivariate MWD. The results help establishing design parameters and optimal operating policies to obtain desired copolymer microstructures.
