| Abstract: | A novel triglyceride containing α,β‐unsaturated ketone was prepared through photoperoxidation from high oleic sunflower oil by two steps one pot environmentally friendly procedure. This new enone‐containing triglyceride was crosslinked with diaminodiphenylmethane (DDM) via aza‐Michael addition. A kinetic study of the reaction of p‐toluidine with either enone‐containing methyl oleate or epoxidized methyl oleate, as model compounds, allowed us to establish the higher reactivity of the former, thus confirming this curing system as an alternative to amine‐cured epoxidized vegetable oils. The thermal properties of thermosets from enone‐ and epoxy‐containing triglycerides with DDM have been evaluated. © 2008 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 46: 6843–6850, 2008 |
