Patent ID: 11015026

Abstract:
The invention relates to polyesters of the following general formula, wherein the residues R1, R2, R3, R4, R5a (as a special case of residue R5), R6, R7 and R8 are free of carboxy, hydroxy, thiol, imino, and primary and secondary amino groups, the residues R5b (as a special case of R5) and R9 contain hydroxyl groups, 10 to 100 mol % of which can be present in salt form analogously to polymers or otherwise capped, u=0 or 1, v=1 to 60 and w=1 to 20. The invention further relates to wetting agents and dispersants that contain the aforementioned polyesters or consist thereof and to a method for producing said wetting agents and dispersants, to the use of the polyesters and reaction products of the method according to the invention as wetting agents and dispersants, and to compositions containing the polyesters, wetting agents and/or dispersants or reaction products of the method according to the invention and particulate solids.
