Our latest work with the title "Tuning thermal properties and biodegradability of poly(isosorbide azelate) by compositional control through copolymerization with 2,5-furandicarboxylic acid" was just published in Polymer Degradation and Stability (IF 5.03).
This study was designed and supervised by Dr Nejib Kasmi, alumni of our lab who is currently a postdoctoral researcher in KTH Royal Institute of Technology.
Highlights
• Novel fully biobased poly(isosorbide azelate) homopolyester (PISAz) and poly(isosorbide furanoate-co-azelate) (PISFAz) copolyesters series were synthesized for first time.
• The controlled incorporation of 2,5-furandicarboxylic acid moiety (FDCA) into polyester backbone proved to be a very efficient route to enhance the thermal properties of PISFAz.
• PISFAz copolyesters with tunable Tg over a high and broad temperature window oscillating from 9 to 91°C depending on FDCA content (vs. Tg of -3°C for PISAz).
• All FDCA-based copolyesters showed enhanced susceptibility to enzymatic degradation with a weight loss in the 25-61% range after 30 days (vs. only 13% for PISAz)
