Intermediate product for the production of lignin polymers and its use for obtaining reagents for the production of composite materials from vegetable fibers, water-resistant paper and cardboard, as well as hard plastics from lignin derivatives.

摘要

RA THE PRODUCTION OF LIGNIN POLYMERS AND THEIR USES OF LIGNIN DERIVATIVES ". D A process for the production of polymers from lignin derivatives from the cellulose industry with phenol oxidizing enzymes is revealed, in the presence of oxidants, characterized by the fact that derivatives for more than 3 hours, in the presence of air, or b) are treated with enzymes for more than 10 minutes, through the passage of air or oxygen, or c) are oxidized by activated treatment , thus obtained, is reacted with non-activated lignin derivatives, forming under polymeric lignin products.
