Date May 23, 1996Redispersable polymer powder compositions are provided which contain homopolymers or copolymers of ethylenically unsaturated monomers and cyclodextrins or cyclodextrin derivatives having the general formula (I), in which n=6, 7 or 8, the substituents R are identical or different and cover H or R1, the substituents R1 are identical or different and cover for optionally substituted C1-C4 -alkyl, carboxy-C1-C4-alkyl, C2-C4-carboxyly residues. Also disclosed are a process for preparing these compositions and their use, as well as polymer dispersions stabilised with cyclodextrins or cyclodextrin derivatives obtained as intermediate products.
