Plant oil-derived triglycerides represent one of
the most abundant and promising classes of renewable raw materials for the
development of bio-based chemicals and polymers. With an annual global
production exceeding 210 million metric tons, plant oils offer an extensive and
sustainable platform for material innovation. These triglycerides are composed
of glycerol esterified with various fatty acids, which contain several reactive
functional groups, including ester linkages, carbon–carbon double bonds,
allylic hydrogen atoms, and α-carbon positions adjacent to the ester group.
These functional sites allow for a wide range of chemical modifications,
enabling the synthesis of both pure compounds and complex polymeric materials.
In a manner analogous to the vulcanization of natural rubber, plant oil
triglycerides can also be crosslinked to enhance their thermal and mechanical
properties. In this study, a novel approach was employed in which plant oils
were polymerized through vulcanization using resoles derived from oil-soluble
phenolic compounds. Methyl oleate, a common fatty acid ester, was selected as a
model compound to investigate the reaction kinetics with p-tert-butyl
phenol-based resole. Following kinetic evaluation, soybean oil, linseed oil,
and cod liver oil were subjected to vulcanization under similar conditions. The
resulting thermoset materials were characterized using thermal and mechanical
techniques, including differential scanning calorimetry (DSC),
thermogravimetric analysis (TGA), and stress–strain testing. Among the oils
tested, vulcanized linseed oil exhibited the most favorable performance, with
superior thermal stability and mechanical strength, demonstrating its potential
for advanced bio-based composite applications.
