Abstract Aliphatic polyesters such as polylactide (PLA) currently deserve particular attention in the area of environmentally degradable polymer materials. PLA is produced via polymerization renewable products, namely lactic acid or lactide. In this work, synthesis done by reactive extrusion ring opening L,L ‐lactide using a continuous single‐stage process which fast and an easy method. The resulting fully characterized solid state NMR. It shown that it exhibits properties similar to those...
A new class of biobased composites with tailorable mechanical properties made natural fibers, polylactic acid, and ferulic acid derivatives (FAD) is studied. FAD was used to develop elastomeric like improved elongation at break highly reversible deformation upon elongation. Composites were prepared using raw enzymatically treated hemp fibers. The fibers defibrillated due the enzymatic treatment increasing their aspect ratio. characterized by reaction fire. No significant change in dispersion...
Thanks to its remarkable properties such as sustainability, compostability, biocompatibility, and transparency, poly-l-lactic acid (PLA) would be a suitable replacement for oil-based polymers should it not suffer from low flexibility poor toughness, restricting use rigid plastic by excluding elastomeric applications. Indeed, there are few fully biobased biodegradable transparent elastomers–PLA-based or not–currently available. In the last decades, many strategies have been investigated...
Poly(3-hydroxybutyrate), PHB, has gathered a lot of attention for its promising properties-in particular biobased nature and high biodegradability. Although PHB is prime candidate the packaging industry, applications are still limited by narrow processing window thermal degradation during melt processing. In this work, three novel additives based on ferulic acid esterified with butanediol, pentanediol, glycerol (BDF, PDF, GTF, respectively) were used as plasticizers antioxidative to improve...
Abstract The homopolymerization in basic conditions of the recently reported bis( γ ‐lactone), 2H‐HBO‐HBO, is herein described for first time. solvent‐free polymerization this pentafunctional levoglucosenone (LGO) derivative affords fully renewable poly(vinyl‐ether lactone) copolymers with a highly hyperbranched structure. This investigation stems from polycondensation trials between 2H‐HBO‐HBO and di(methyl carbonate) isosorbide (DCI) that fails to give anticipated polycarbonates. Such...
Abstract This work reports a facile route to synthesize homochiral and stereocomplexed polylactide by reactive extrusion. The effect of the polymerization catalyst (combination tin(II)octanoate triphenylphosphine) before after its deactivation is discussed. Poly‐ L ‐lactide (PLLA) exhibits crystallinity diblock poly‐ , D (PDLLA) stereocomplex crystallinity. presence residual monomer leads plasticizing effect, reducing glass transition temperature ( T g ). Changes tacticity ‐tacticity) are...

Our permits make matrix able form stereocomplex crystallinity incorporate flame‐retardant additives during synthesis at same time. material can be molded keeping its...
Poly-β-hydroxybutyrate (PHB) is a very common bio-based and biocompatible polymer obtained from the fermentation of soil bacteria. Due to its important crystallinity, PHB extremely brittle in nature, which results poor mechanical properties with low extension at break. To overcome these issues, crystallinity can be reduced by blending plasticizers such as ferulic acid derivatives, e.g., bis-O-dihydroferuloyl-1,4-butanediol (BDF). The degradation potential blends containing various...
