Abstract : Ultraviolet spectrophotometry is used to show the presence of rosin or ester gum modifications in the unsaponifiable portion of an isolated alkyd coating vehicle. Phenolic resins are similarly detected in either the unsaponifiable portion or in the oil acids fraction if they are saponified. Phenolic resins are readily detectable; however, the method is limited to 5%, on the non-volatile basis, of rosin or ester gum. (Author)
