Anti-Ultraviolet Biobased Polyesters Synthesized by Acyclic Diene Metathesis Polymerization
Synthesis of copolymers using 2,5-furandicarboxylic acid (FDCA) and isosorbide (IS) as renewable feedstocks remains a challenge in conventional melt polycondensation. Herein, acyclic diene metathesis (ADMET) polymerization of several kinds of α,ω-dienes containing an FDCA or IS moiety was performed under mild conditions to afford biobased polyesters with an unsaturated chain structure and tunable glass transition temperature between −40 and 34 °C. Meanwhile, FDCA-derived α,ω-diene was used as a comonomer to undergo inverse vulcanization with elemental sulfur, affording a polysulfide as the cross-linking agent suitable for modifying ADMET polyesters. The cross-linked polyesters showed improved mechanical properties and good reprocessability. Furthermore, the modified polyester composites exhibited excellent anti-ultraviolet (UV) performance with a high UV protection factor of 251 and maintained almost the original mechanical properties even after 72 h of UV light exposure. This work provided a practical approach for the high-value-added utilization of ADMET polyesters as sustainable functional materials.
期刊介绍:
Macromolecules publishes original, fundamental, and impactful research on all aspects of polymer science. Topics of interest include synthesis (e.g., controlled polymerizations, polymerization catalysis, post polymerization modification, new monomer structures and polymer architectures, and polymerization mechanisms/kinetics analysis); phase behavior, thermodynamics, dynamic, and ordering/disordering phenomena (e.g., self-assembly, gelation, crystallization, solution/melt/solid-state characteristics); structure and properties (e.g., mechanical and rheological properties, surface/interfacial characteristics, electronic and transport properties); new state of the art characterization (e.g., spectroscopy, scattering, microscopy, rheology), simulation (e.g., Monte Carlo, molecular dynamics, multi-scale/coarse-grained modeling), and theoretical methods. Renewable/sustainable polymers, polymer networks, responsive polymers, electro-, magneto- and opto-active macromolecules, inorganic polymers, charge-transporting polymers (ion-containing, semiconducting, and conducting), nanostructured polymers, and polymer composites are also of interest. Typical papers published in Macromolecules showcase important and innovative concepts, experimental methods/observations, and theoretical/computational approaches that demonstrate a fundamental advance in the understanding of polymers.
