Der Einfluß stereoisomerer und konjugierter Fettsäuren,insbesondere dehydratisierter Rizinusöl-Fettsäuren,auf die Eigenschaften von Alkydharzen

The Influence of the Stereoisomeric and Conjugated Fatty Acids, Especially Dehydrated Castor Oil Fatty Acids, on the Properties of Alkyd Resins Alkyds with 60% oil content were prepared from the drying oils with different contents of conjugated and stereoisomeric fatty acids, specially dehydrated castor oil, and the autoxidation and film forming properties of these were investigated. Trans-trans-dienoic fatty acids oxidised fastest but hindered the through-drying. Throughdrying is dependent on this hinderence and the total content of conjugated dienoic fatty acids. The hardness of the film, measured after 7 days by Sward-Rocker method, is a function of the total amount of conjugated and nonconjugated polyunsaturated fatty acids.
