    Abstract: The present invention relates to a process for the production of moldings from finely divided materials based on lignocellulose, and the moldings obtainable thereby. The invention also relates to the use of aqueous compositions which comprise at least one crosslinkable urea compound for the preparation of finely divided materials based on lignocellulose and treated with this composition for the production of moldings.

Date Feb. 9, 1995Sulfonated and oxidized indene polymers obtainable by (a) polymerization of indene or indene derivatives of the general formula I I where R1 is hydrogen, methyl or ethyl and n is 1 or 2, or of mixtures which contain the compounds I as well as other copolymerizable and/or non-polymerizable organic compounds in an amount of at least 10% by weight, b) sulfonation of the polymer with a sulfonating agent at from 40 DEG to 130 DEG C., and c) non-chain-degrading oxidation of the polymer at from 80 DEG to 180 DEG C. These indene polymers are suitable for use as dispersants for example in dye and pigment preparations.
