Abstract
A method for preparing a thermosetting binder composition, includes mixing at least one lignin, at least one organic monocarboxylic or sulfonic acid, and at least one organic non-polymeric polycarboxylic acid, and heating the mixture at a temperature of between 90° C. and 170° C., for a duration of between 5 seconds and 5 minutes so as to form at least one water-soluble or water-dispersible lignin ester.
