Abstract
Fats and fatty acids are polymerized by oxidative or thermal processes. Structures have been deduced by using a number of chemical and physical techniques. General methods applicable to the analysis of polymerized oils include determinations of acetone number, iodine value (I.V.), molecular weight, dielectric constant, viscosity, and refractive index. Monomers, dimers, and trimers are separated generally by molecular distillation. In addition, urea fractionation and a number of chromatographic techniques are useful for the detection of monomers, dimers, and polymers.Keywords
