    Abstract: The present invention relates to the use of water soluble or water dispersible polymers containing carboxyl groups, optionally in latent form, and side-chains of general formula (I) -X-Y-[-O-(-Alk-O) n -R] k as additives in mineral building materials, wherein X, Y, Alk, R, n and k have the meanings cited in claim 1. Said polymers can be obtained by polymerizing ethylenically unsaturated monomers in the presence of compounds containing phosphorus and, optionally, by additional polymer-analogous transformation. The invention further relates to the production of said polymers and the use thereof. Also described are polymers, which can be obtained by polymerizing aromatic vinyl compounds, olefins, cycloolefins and/or dienes, as D monomers and anhydrides of ethylenically unsaturated dicarboxylic acids as E monomers and which can be used both as parent compounds for the above-mentioned polymers and as additives for mineral building materials.

    Abstract: Preparation of the trisodium salt of isoserine-N,N-diacetic acid (I) by reaction of acrylonitrile with aqueous hydrogen peroxide to give glycidamide (II) and further reaction of II with the disodium salt of iminodiacetic acid (III) to give I, by carrying out the process continuously and, in it, successively a) reacting together acrylonitrile and aqueous hydrogen peroxide at pH 7-8 and 30-60 DEG C, b) removing unreacted acrylonitrile by distillation, c) passing the reaction mixture over a solid hydrogen peroxide-decomposing catalyst, d) reacting the aqueous solution of II, obtained in this way, with III at pH 7-9 and 40-90 DEG C, e) reacting the resulting solution with a basic sodium compound at pH 9-14 and 60-95 DEG C, f) removing the ammonia which is produced by distillation and g) if desired, working up the aqueous solution of I, obtained in this way, in a manner known per se to give solid I.
