Title: | Co-Polymers based on Poly(1,4-butylene 2,5-furandicarboxylate) and Poly(propylene oxide) with Tuneable Thermal Properties: Synthesis and Characterization | Authors: | Matos, Marina Sousa, Andreia F. Mendonça, Patrícia V. Silvestre, Armando J. D. |
Keywords: | 2,5-Furandicarboxylic acid; poly(propylene oxide); poly(ester-ether) co-polymers; tuneable thermal properties | Issue Date: | 21-Jan-2019 | Publisher: | MDPI | Project: | FCT and POPH/FSE are gratefully acknowledged for funding a doctoral grant to MM (PD/BD/52501/2014) and the post-doctoral grant of PVM (SFRH/BPD/117589/2016). The costs resulting from the FCT hiring of AFS was funded by national funds (OE), through FCT – Fundação para a Ciência e a Tecnologia , I.P., in the scope of the framework contract foreseen in the numbers 4, 5 and 6 of the article 23, of the Decree-Law 57/2016, of August 29, changed by Law 57/2017, of July 19. This work was developed within the scope of the project CICECO-Aveiro Institute of Materials, FCT Ref. UID/CTM/50011/2019, financed by national funds through the FCT/MCTES. | Serial title, monograph or event: | Materials | Volume: | 12 | Issue: | 2 | Abstract: | Poly(ether ester)s (PEEs) represent a promising class of segmented co-polymers, nevertheless the synthesis of PEEs based on renewable 2,5-furandicarboxylic acid (FDCA) is still scarce. In this context, a series of poly(1,4-butylene 2,5-furandicarboxylate)-co-poly(poly(propylene oxide) 2,5-furandicarboxylate) co-polyesters with different composition of stiff poly(1,4-butylene 2,5-furandicarboxylate) (PBF) and soft poly(poly(propylene oxide) 2,5-furandicarboxylate) (PPOF) moieties were synthesized, via a two-step bulk polytransesterification reaction. The molar ratio of PBF/PPOF incorporated was varied (10 to 50 mol%) in order to prepare several novel materials with tuned properties. The materials were characterised in detail through several techniques, namely ATR FTIR, ¹H and 13C NMR, TGA, DSC, DMTA and XRD. Their hydrolytic and enzymatic degradation evaluation was also assessed. These new co-polymers showed either a semi-crystalline nature when higher PBF/PPOF ratios were used, and for approximately equal amounts of PBF and PPOF an amorphous co-polyester was obtained instead. | URI: | https://hdl.handle.net/10316/107150 | ISSN: | 1996-1944 | DOI: | 10.3390/ma12020328 | Rights: | openAccess |
