Synthesis and further modification of AESO.
These fully bio-based polymers derived from vegetable oil and sugar can be
used as environmentally friendly renewable materials for bio-medical and
other applications. With similar concerns, Ma et al.

synthesized a rosin-
based diacrylate which is also a bio-based derivative, and serves as a rigid
monomer. AESO is co-polymerized with the rigid monomer and the cured
AESO has enhanced mechanical and thermal properties, especially the T
g
,
tensile strength and tensile modulus, compared with divinylbezene. This is
another example of a fully bio-based thermosetting resin with promising
mechanical properties. Janes et al.

used the advantages of photo-
polymerization to produce chemically stable fibers containing over 50 wt%
AESO with an average diameter of 30 mm without applied heat or solvents.
