Research on High-Purified Lignin Thermoplastics
Highly purified lignin with 3000 molecule weight, more than 90% purity, was obtained from reed pulp, through the use of organic-solvent-circulation method, a newly lignin separating method. Organic-solvents-circulation method of lignin separation exhibited faint effects on the molecule structure of lignin. Melting lignin showed pseudoplastic characteristics. Lignin blending performed excellent processing properties in molding process.
