A series of furan-aromatic polyesters were successfully synthesized via direct esterification method starting from 2,5-furandicarboxylic acid, ethylene glycol, 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol, and 1,8-octanediol and characterized by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (¹H NMR), X-ray diffraction (XRD), differential scanning calorimeter (DSC), thermogravimetric analysis (TGA), dynamic mechanical analysis (DMA), tensile tests, and so on. The preliminary evidence clearly showed that direct esterification method was rewarding and worthy to synthesize these furan-aromatic polyesters. The densities of furan-aromatic polyesters were ranging from 1.19 to 1.38 kg/m³. The FTIR and ¹H NMR confirmed their expected structures in detail. The results of XRD showed that these furan-aromatic polyesters were crystalline polyesters. The results of DSC, TGA, DMA, and tensile tests showed that they behaved as thermoplastic polyester, had satisfactory thermal and mechanical properties, and their thermal stabilities were quite similar to that of corresponding benzene-aromatic polyesters. The results of contact angle measurement showed that they were hydrophilic. The properties above showed that furan-aromatic polyesters based on renewable resources could be a viable alternative to their successful petrochemical benzene-aromatic counterpart. Furthermore, they could be used as biopolymer materials according their satisfactory thermal and mechanical properties and hydrophilicity in the future. © 2011 Wiley Periodicals, Inc.

Monodisperse cyano-functionalized porous polymeric beads were synthesized by seeded polymerization; these microparticles were further used as support for zirconocene catalyst, which performed as a solid homogeneous catalyst in ethylene polymerization. © 2011 Wiley Periodicals, Inc.
