Thermal reaction of safflower oil in the presence of manganese iodide was investigated under the following reaction conditions : 0.065 mol/kg, 220°C, 0.13 mol/kg, 220°C; 0.26 mol/kg, 200°C ; 0.26 mol/ kg, 220°C. <BR>The fatty acid compositions of reaction products were determined by means of GLC and UV methods. Conjugated dienes formed but monoenoic acid did not increase during the reaction. When safflower oil was heated in the presence of manganese iodide 0.26 mol/kg, at 220°Cfor 3h, remarkable amounts of residue were formed which contained mainly polymerization products, ca. 1.6% decomposition products and ca. 3.9% manganese soap. <BR>The GPC analysis of the polymerization product showed that it was composed of dimers, trimers, tetramers, and higher oligomers of fatty acids.
