Process optimization for the production of bio-resins using de-polymerized lignin

摘要

1. At low percent substitutions, BPF resole qualities are similar to those of pure PF resoles; 2. Relevance of observing BPF qualities at high percent substitutions; 3. High percent substitution: acceptable shear strength, lower wood failure, and exceedingly high viscosity measurements; 4. Increasing F/P ratio reduces the curing temperature and increases the shear strength; 5. Increasing Lignin Mw reduced the curing temperature and increases the shear strength while also increasing the viscosity.
