Water-soluble or water-dispersible polymers containing a carboxyl group, optionally a latent form of a carboxyl group and side chains of the general formula (I) are used as additives in the inorganic building material:n n n Formula In n n n n n n n In the above formula,n n n X, Y, Alk, R, n, k are defined in claim 1, which can be prepared by polymerizing ethylenically unsaturated monomers in the presence of a phosphorus containing compound, and performing polymer-cognate conversion reactions as necessary. do.n n n Such polymers and methods for their preparation are also provided in the present invention.n n n Also disclosed are polymers obtained by polymerizing vinylaromatic compounds, olefins, cycloolefins and / or dienes as monomer D and ethylenically unsaturated dicarboxylic acids as monomer E. These can all be used as starting materials for the aforementioned polymers and as additives in inorganic building materials. |
