	abstract = {A new bio-based biphenylene-containing diisocyanate, namely, 5,5{\textquoteright}-diisocyanato-2,2{\textquoteright},3,3{\textquoteright}-tetramethoxy-1,1{\textquoteright}-biphenyl (BDI) was synthesized starting from vanillic acid - a lignin-derived phenolic acid. A series of new partially bio-based polyimides was prepared by polycondensation of BDI with five commercially available aromatic dianhydrides. Polyimides exhibited good solubility in organic solvents and medium molecular weights (Mn (GPC, polystyrene standard) = 25,100-32,200 g mol(-1)). Polyimides showed good thermal stability with 10\% degradation temperature and glass transition temperature in the range 459-473 degrees C and 262-329 degrees C, respectively.},
