A series of cardanol derivatives prepared in a preceding study 1 are evaluated as PVC plasticizers. These include butyl anacardate (3), cyclohexyl anacardate (4), 3‐(pentadec‐8′‐enyl)phenyl acetate (5), 3‐(8′,9′‐diacetoxypentadecyl)phenyl acetate (6), and 3‐(8′‐epoxypentadecyl)phenyl acetate (7). The evaluation initially involves compatibility and Brabender plastification testing. The two acetates 6 and 7 as the most promising compounds are selected for further investigation, comprising the determination of tensile properties and thermal stability behavior of compression‐molded plasticized PVC sheet material. The extrudability of a plasticized wire coating formulation is also studied. The plasticizing efficiency of both 6 and 7 is on a par with di(2‐ethylhexyl) phthalate used as a standard plasticizer. In addition, both acetates show distinct costabilizing efficiency, the expoxyacetate 7 in this respect being superior to the other compounds tested. Cardanol, readily available as a by‐product of cashew nut processing, thus may represent a welcome addition to the strained raw material market in the plasticizer field.
