ABSTRACT:
The invention relates to aqueous compositions, preferably aqueous compositions comprising at least one polymer with a particle size of more than 10 μm, formed from the polymerisation of a) at least one monomer of formula (I), wherein R1, signifies hydrogen or methyl, R2signifies hydrogen or C1-C4alkyl, R3signifies C1-C4alkylene, R4, R5and R6signify independently from each other hydrogen or C1-C4alkyl, X signifies —O— or —NH— and Y signifies Cl; Br; l; 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.
