Glucaric Acid
Glucuronic Acid

A research team at North Carolina State University says biobased glucaric-acid or lignin additives can dramatically increase the toughness of polyvinyl alcohol fibers.
As a new anti-plasticizer, the additive can nearly triple the resin's tensile strength and double its modulus, and the enhanced PVA fibers can find uses in biofriendly products such as fibers and polymers, detergents, paints and diapers.
Petrol and biochemical plasticizers are added to poly(vinyl alcohol) (PVA) to improve its processability while tuning its moisture sensitivity. But those additives often reduce the mechanical performance of PVA products. In this study, the antiplasticization and properties of PVA containing additives from biorenewable sources are studied.
Volume I: Results of Screening for Potential Candidates from Sugars and Synthesis Gas
This report identifies twelve building block chemicals that can be produced from sugars via biological or chemical conversions. The twelve building blocks can be subsequently converted to a number of high-value bio-based chemicals or materials.
Building block chemicals, as considered for this analysis, are molecules with multiple functional groups that possess the potential to be transformed into new families of useful molecules.
The twelve sugar-based building blocks are 1,4-diacids (succinic, fumaric and malic), 2,5-furan dicarboxylic acid, 3-hydroxy propionic acid, aspartic acid, glucaric acid, glutamic acid, itaconic acid, levulinic acid, 3-hydroxybutyrolactone, glycerol, sorbitol, and xylitol/arabinitol.
