http://willson.cm.utexas.edu/Teaching/Chem367L392N/Files/Lecture%2013.pdf The Mayo–Lewis equation or copolymer equation in polymer chemistry describes the distribution of monomers in a copolymer. It was proposed by Frank R. Mayo and Frederick M. Lewis. The equation considers a monomer mix of two components $${\displaystyle M_{1}\,}$$ and See more Monomer 1 is consumed with reaction rate: $${\displaystyle {\frac {-d[M_{1}]}{dt}}=k_{11}[M_{1}]\sum [M_{1}^{*}]+k_{21}[M_{1}]\sum [M_{2}^{*}]\,}$$ with See more • copolymers @zeus.plmsc.psu.edu Link See more Reactivity ratios indicate preference for propagation.
