Novel bio-derivable tricyclic oxanorbornene polymers have been prepared via ROMP using secondary furfurylamine and maleic anhydride derived monomers. These polymers exhibit thermal reversible crosslinking and self-healing properties, showing potential for various applications in the future.
Novel bio-derivable tricyclic oxanorbornene polymers, based upon secondary furfurylamine and maleic anhydride derived monomers, prepared via ring opening metathesis polymerization (ROMP) are reported. The tricyclic oxanorbornenes with fused lactam ring are exo Diels-Alder adducts. DFT calculations support the cycloaddition is the first step, followed by lactamization. The polymerizations are rapid and deliver polymers with targeted molar mass and low dispersity (D). The prepared polymers with furanyl pendant groups have reactivity towards maleimide-bearing compounds to form thermally induced crosslinked networks through thermoreversible Diels-Alder reactions. The thermoreversible (self-healing) behavior is confirmed by sol gel transition. This new class of bio-derived polymer could be further modified with different active moieties as pendant groups and hence be tailored for more applications in the future. [GRAPHICS] .
