The vegetable oil extraction process can interfere with the characteristics of the final product, including
color and unsaturated quantity. However, no study has analyzed this effect in vegetable oil-based polymeric
materials. Therefore, this work evaluates two different extraction methods for passion fruit vegetable
oil and their influence on polymeric materials, comparing the results with one polymer obtained by
commercial vegetable oil. The polymers syntheses were performed in the absence of solvent nor catalyst
and performed by conventional heating. Properties as iodine values and fatty acid profile did not vary
significantly among the oils. However, color and thermal stability varied between the vegetable oils,
especially due to the presence of small molecules that can be extracted during the Soxhlet process. As a
result, the final polymers also presented different colors. For this type of polymerization, the extraction
processes did not interfere significantly in thermal stability, glass transition, spectroscopic data nor
morphological properties of final polymers.
