Binder mixture modified with lignin and process for producing the same.

摘要

The invention relates to novel binders obtained by reacting low-molecular-weight lignin from the organosolv process with phenol and formaledhyde. These novel binders are suitable, alone or mixed with conventional phenol-novolaks, for the preparation of curable moulding compositions and high-temperature-resistant moulded materials, refractory products and carbon materials and for the production of friction coatings and textile nonwovens.
