Figure 16. Calculated percentage of propyl (green, closed circles) and butyl (black, open circles) salicylate in PS:BS binary mixtures determined from the integrated NMR hydroxyl peak vs. known PS gravimetric weight percentage. The R² value for these lines of best fit is poor, reflecting difficulties in deconvoluting overlapping peaks. Furthermore, since the methyl peaks for these two compounds are not resolved, no usable data could be extracted from that region.
