Abstract

A novel lignocellulose-based poly(butylene 3-propyladipate-co-furanoate) (PBA_pF) was synthesized from lignocellulose-derived 3-propyladipic acid (3PAA), 1,4-butanediol (BDO), and 2,5-furandicarboxylic acid (FDCA). The copolyesters were characterized by ¹H NMR, GPC, DSC, TGA, XRD, DMA, rotational rheology, tensile tests, and enzymatic degradation tests. They were random copolymers whose composition was well controlled, and the number-average sequence lengths of the copolyesters were around 1.35-4.33. By combining the results of tensile tests and DMA, the elongation at break of PBA_pF₄₅ (1865%) had a much greater value than that of PBAF₄₅ (1250%), i.e., the branching incorporated into the linear polymer increased the melt strength and conferred tension-hardening properties, which helped to enhance the elongation of the polymer. In addition, the influences of 3PAA content on enzymatic degradation were studied in terms of weight loss; when the content of 3PAA was 55 mol%, the copolyesters exhibited good biodegradability. Thus, depending on their composition, PBA_pF_S might find end applications as biodegradable elastomers or impact modifiers for other polymers.

期刊介绍： Molecules (ISSN 1420-3049, CODEN: MOLEFW) is an open access journal of synthetic organic chemistry and natural product chemistry. All articles are peer-reviewed and published continously upon acceptance. Molecules is published by MDPI, Basel, Switzerland. Our aim is to encourage chemists to publish as much as possible their experimental detail, particularly synthetic procedures and characterization information. There is no restriction on the length of the experimental section. In addition, availability of compound samples is published and considered as important information. Authors are encouraged to register or deposit their chemical samples through the non-profit international organization Molecular Diversity Preservation International (MDPI). Molecules has been launched in 1996 to preserve and exploit molecular diversity of both, chemical information and chemical substances.
