摘要

"The use of polu00ecmeros water soluble or dispersible in water, polu00ecmero, copolu00ecmero, and process for the preparation of the polu00ecmero water soluble or dispersible in water.The present invention relates to the use of polymers which are soluble in water, or water dispersible, containing carboxyl groups, optionally in the form of latentAnd side chains with general formula (I): - X - Y - [- O - (ALK) n - R] K as additives in mineral materials for construction, where x, y, ALK, R, N and K have the meanings given in claim 1.These polymers can be obtained by the above polymerization of monomers in the presence of etilenicamente unsaturated compounds containing phosphorus and, optionally,For further processing along the polymer. The invention is also related to the production of the mentioned polymers and use of the same.Also described are polymers that can be obtained by the polymerization of vinyl aromatic compounds, olefins,Cicloolefinas and / or dienes as monomers D and anhydrides of dicarboxylic acids etilenicamente unsaturated as monomers and.And that can be used both as compounds similar to the above mentioned polymers or as additives for mineral materials for construction.
