Figure 12. Calculated percentage of ethyl (blue, closed circles) and propyl (green, open circles) salicylate in ES:PS binary mixtures determined from the integrated NMR hydroxyl peak vs. known ES gravimetric weight percentage. The R2 value for these lines of best fit is poor, reflecting difficulties in deconvoluting overlapping peaks
