Renewable resources based polymers: Synthesis and characterization of 2,5-diformylfuran-urea resin
Condensation of renewable resources based monomer 2,5-diformylfuran (DFF) and urea at 110 °C by melting a solid mixture gives a crystalline polymer resin in 90% yield. This resin was characterized by elemental analysis, 1H, 13C and 1H-1H COSY NMR, IR, UV, TGA and DTA. The structural unit of this new material consists of one DFF molecule condensed with two urea molecules at the aldehyde group of DFF. A homologous resin was prepared by using 5,5′-oxydimethylenebis(2-furaldehyde) and urea in 84% yield via a similar procedure and characterized as well. © 2009.
