A furan-based synthetic
biopolymer composed of a bifuran monomer
and ethylene glycol was synthesized through melt polycondensation,
and the resulting polyester was found to have promising thermal and
mechanical properties. The bifuran monomer, dimethyl 2,2′-bifuran-5,5′-dicarboxylate,
was prepared using a palladium-catalyzed, phosphine ligand-free direct
coupling protocol. A titanium-catalyzed polycondensation procedure
was found effective at polymerizing the bifuran monomer with ethylene
glycol. The prepared bifuran polyester exhibited several intriguing
properties including high tensile modulus. In addition, the bifuran
monomer furnished the polyester with a relatively high glass transition
temperature. Films prepared from the new polyester also had excellent
oxygen and water barrier properties, which were found to be superior
to those of poly(ethylene terephthalate). Moreover, the novel polyester
also has good ultraviolet radiation blocking properties.
