Manker, Lorenz P. published the artcileSustainable polyesters via direct functionalization of lignocellulosic sugars, Recommanded Product: Pentane-1,5-diol, the publication is Nature Chemistry, database is CAplus and MEDLINE.
The development of sustainable plastics from abundant renewable feedstocks was limited by the complexity and efficiency of their production, as well as their lack of competitive material properties. Here the authors demonstrate the direct transformation of the hemicellulosic fraction of nonedible biomass into a tricyclic diester plastic precursor at 83% yield (95% from com. xylose) during integrated plant fractionation with glyoxylic acid. Melt polycondensation of the resulting diester with a range of aliphatic diols led to amorphous polyesters (Mn = 30-60 kDa) with high glass transition temperatures (72-100°), tough mech. properties (ultimate tensile strengths of 63-77 MPa, tensile moduli of 2,000-2,500 MPa and elongations at break of 50-80%) and strong gas barriers (oxygen transmission rates (100 μm) of 11-24 cc m-2 day-1 bar-1 and H2O vapor transmission rates (100 μm) of 25-36 g m-2 day-1) that could be processed by injection molding, thermoforming, twin-screw extrusion and 3-dimensional printing. Although standardized biodegradation studies still need to be performed, the inherently degradable nature of facilitated their chem. recycling via methanolysis at 64°, and eventual depolymerization in room-temperature H2O.
