The present invention relates to the use of water-soluble or
water-dispersible polymers as additives in mineral building materials.
The novel polymers are obtainable by polymerizing alkoxylated derivatives
of 3-allyloxy-1,2-propanediol with ethylenically unsaturated mono- or
dicarboxylic acids or the anhydrides, esters or mixtures thereof and, if
appropriate, with one or more further ethylenically unsaturated monomers
