Abstract

Abstract: The use of bio-based plasticizers with low toxicity and good compatibility with polyvinyl chloride (PVC) has attracted more attention in the recent years. With bio-based 2, 5-furandicarboxylic acid (FDCA) and butyl oligo-glycol ethers as raw materials, three liquid furan-based plasticizers of di(butyl glycol) furan-2, 5-dicarboxylate, di(butyldiglycol) furan-2, 5-dicarboxylate and di(butyltriglycol) furan-2, 5-dicarboxylate were synthesized by direct esterification. The chemical structure of three plasticizers was characterized with FTIR, 1 H NMR and 13 C NMR. From DMA measurement, the glass transition temperature (Tg ) of the plasticized PVC was decreased gradually when furan-based plasticizers were added to PVC formulation from 30 up to 50 phr. Due to lots of ether bonds in furan-based plasticizers, they expressed over two-fold lower migration in organic solvent compared with the traditional plasticizer diethylhexyl phthalate (DEHP). Through the characterization of elongation at break, hardness and thermal stability, furan-based plasticizers presented the same plasticization properties as DEHP, and had potential industrial application prospects. Highlights: Three liquid plasticizers are synthesized by 2, 5-furandicarboxylic acid and butyl olio-glycol ethers. Full bio-based plasticizer. Ether bonds are introduced to the structure of plasticizers' branch chains. Similar or better mechanical properties than DEHP. High properties about anti-migration in organic solvent.
