Process for the production of lignin-containing polymers |
March 4, 1997 |
| Polymers containing lignin and organic compounds are produced by polymerizing the lignin with organic compounds containing at least 3 carbon atoms as well as oxygen, nitrogen and/or multiple-linkage functions in the presence of radically oxidizing enzymes and of oxidation products co |

Process for producing a binder for wood materials |
February 21, 1984 |
| A process in which phenolic substances, particularly lignin sulfonate, are used to produce a binder for wood materials. The phenolic substance is activated by displacing it with enzymes. Phenolic groups of the phenolic substance become oxidatively polymerized by a radical mechanism, so t |
