Abstract : The acid number of low molecular weight p-tert-butylphenol-formaldehyde-salicylic acid copolymer was determined with less than 7% error either by titration of a dioxane solution with methanolic KOH in the presence of bromophenol blue, or by measurement of the 1660 cm-anion(1) peak in the IR spectrum.
