    摘要： A process for polymerizing unsaturated fatty acids comprises heating the fatty acids in the presence of a catalytic proportion of an unactivated clay and water. The product polymerizate is distilled to separate unreacted monomer acids which are separately polymerized under similar conditions. Higher overall polymer yields are obtained.
