As the increasing concerns about the environmental protection and fossil resource issues, it is important to develop biobased polymer materials from renewable biomass resources. As one of the most valuable biogenic platform compounds, furandicarboxylic acid and derivatives, have attracted much attention in synthesis of fine chemicals and biobased materials. In recent years, varied biobased polyamide homo-and copolymers have been successfully prepared via polycondensations between furandicarboxylic acid and derivative and diamines, including melt polymerization, solution polymerization, interfacial polycondensation, and solid phase polycondensation. Herein, recent progress in synthesis of renewable furan-containing polyamides are detail introduced. Polyamides with different structures present favorable thermal properties and mechanical performance. In the meantime, varied measures have been taken to improve the molecular weight, yield, catalytic efficiency, structural diversity, etc. Moreover, the challenges and modifications of biobased furan-containing polyamides for further industrial applications are discussed and prospected.
