Despite their compositional differences, both feedstocks produced nearly 100% anisotropic content.

The models indicate that LEO contains more aromatics, smaller molecular size, shorter branched chains, and richer methylene-bridged structures than DOA. Aromatic oligomerization is the primary reaction occurring during thermal condensation. Variations in molecular structure lead to significant differences in the properties of the resulting MP.
