ENZYMATISCH MODIFIZIERTE LIGNINE
The present invention relates to water-soluble modified lignins preparable by enzymatic reaction of at least one water-insoluble lignin with at least one organic compound which possesses at least one group selected from primary or secondary amino group, hydroxyl group and phenyl group and has an average molecular weight in the range from 75 to 2500 g/mol. The water-soluble modified lignins are preparable under mild conditions in a simple process. They can be used as dispersants for mineral binder compositions, where they act as plasticizers and in so doing prolong the setting time to much less of an extent than the water-insoluble lignins used in their preparation.
