5. Using the data in the table below for reactivity ratios in free radical copolymerizations, calculate and plot F1 versus f1 for the following systems. Also determine the number average sequence length (Nm) for both monomers and draw approximate structures of the copolymers assuming you use 50% Monomer 1 and 50% Monomer 2 in the polymerizations.
