Since a preliminary study had shown that the internal double bonds present on the unsaturated aliphatic chains were too unreactive for any viable polymerization process, chemical modifications were investigated involving the grafting of polymerizable moieties on hydroxy or epoxide groups present in castor oil or in epoxidized soybean oil. Acrylate and styrenic urethane moieties were successfully appended on these triacylglycerol molecules. The grafting processes are described and the modified oils characterized, leading to the discussion of some structure‐property relationships.
