Publication number: 20120012035Abstract: A method for producing chemically modified lignin decomposition products. To this end, a lignin-containing starting material is decomposed into low-molecular and high-molecular lignin decomposition products under acid conditions in the presence of a liquid medium, and the low-molecular lignin decomposition products are at least largely separated in order to obtain a high-molecular fraction. Subsequently, the high-molecular lignin decomposition products present in the high-molecular fraction are converted into chemically modified lignin decomposition products. The chemically modified lignin decomposition products obtained in this way can be used, for example, as dispersing agents, complexing agents, phenol component, flocculant, thickener or auxiliary agents for cementous systems, coatings, paints or adhesives.Type: ApplicationFiled: March 19, 2010Publication date: January 19, 2012Applicant: SIKA TECHNOLOGY AGInventors: Norman Blank, Irene Schober, Philipp Rudolf Von Rohr, Tobias Voitl
