| 摘要 |
The invention relates to aqueous compositions, preferably aqueous compositions comprising at least one polymer with a particle size of more than 10 mum, formed from the polymerisation of a) at least one monomer of formula (I), wherein R<SUB>1</SUB>, signifies hydrogen or methyl, R<SUB>2 </SUB>signifies hydrogen or C<SUB>1</SUB>-C<SUB>4</SUB>alkyl, R<SUB>3 </SUB>signifies C<SUB>1</SUB>-C<SUB>4</SUB>alkylene, R<SUB>4</SUB>, R<SUB>5 </SUB>and R<SUB>6 </SUB>signify independently from each other hydrogen or C<SUB>1</SUB>-C<SUB>4</SUB>alkyl, X signifies -O- or -NH- and Y signifies Cl; Br; I; hydrogen-sulphate or methosulfate, b) and/or at least one non-ionic monomer, c) at least one cross-linking agent in an amount of 0-50 ppm by the weight of component a) and b) optionally at least one chain transfer agent with the proviso that (i) if the polymer is a cationic homopolymer then the amount of the crosslinking agent is always more than 0 ppm and less than 50 ppm.
