a-Sketch the graph of mole fraction in feed (f) versus instantaneous mole fraction in the copolymer (F) for the styrene/methyl methacrylate copolymer using the copolymer equation. For free radical polymerization, r1 and r2 are 0.52 and 0.46 respectively. However, if you catalyze these reactants using cationic polymerization, you get different r1 and r2 of 10 and 0.1 respectively.
b-From the graph, describe the difference in initial sequences for the two cases if you start with an equimolar styrene-methyl methacrylate feed.
