in the literature over the past seventy years; however, they are fundamentally inaccurate and have since been made unnecessary by simple integrated approaches utilizing modern computational tools. That is, data for comonomer consumption over the course of a single copolymerization reaction can be fit to extract reactivity ratios simply and accurately through numerical integration of the Mayo-Lewis equation. Moreover, a simple, closed-form integrated solution of the Mayo-Lewis equation was derived by Meyer and Lowry in 1965: 𝑐𝑜𝑛𝑣. = 1 -3
