Abstract
Abstract Polymerization of 2,5-furandicarbonyl chloride with bisphenol A in four systems was studied. Catalysed polymerizations in tetrachloroethane solution at 155°C using AlCl 3 or Zn dust yielded coloured polymer with intrinsic viscosities of 0.24 and 0.23, respectively in about 80% yield. Uncatalysed solution polymerization in chloroform at ambient temperature using triethylamine as an acid acceptor gave a 90% yield of a white, film-forming polymer with an intrinsic viscosity of 0.5. Interfacial polymerization in benzene yielded a polymer of the same viscosity but in reduced yield (16%). Thermal analysis by differential scanning calorimetry revealed that thermal decomposition begins at about 225°C and is superimposed on an apparent crystallization exotherm at ∼250°C and an apparent melting endotherm at ∼320°C.
