Figure 13. Calculated percentage of ethyl (blue, closed circles) and propyl (green, open circles) salicylate in ES:PS binary mixtures determined from the integrated NMR terminal methyl peak vs. known ES gravimetric weight percentage. The high R2 value for these lines of best fit reflect the high correlation between the two data sets. The excellent peak resolution aids the data quality
