Patent attributes
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, R2 signifies hydrogen or C1-C4alkyl, R3 signifies C1-C4alkylene, R4, R5 and R6 signify 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.
