365Vegetable Oils for Green Composites
The free-radical polymerization of triglyceride double bonds has received little
attention due to the presence of chain-transfer processes to the many allylic positions in
the molecule. However, some vegetable oils such as linseed and TUNs have been found
to be susceptible to free-radical polymerization and classically exploited as drying oils
because the drying power of these oils is directly related to their highly unsaturated
nature (Tallman et al. 2004). These oils are used mostly in paints and coatings, and also
in inks and resins since drying oils will auto-oxidize in the presence of oxygen from a ...
