Abstract: Aromatic emulsifier mixture with high stability for e.g. acrylate polymer, adhesive, binder or impregnation contains sulfonyl compound. Aromatic emulsifier mixture comprises a compound of formula (I) and a compound of formula (II): R -O-(Z-O)n-SO3 K (II) X = O, S, CH2, NH or NR ; One or two of R - R = SO3 K and the remainder = H or 1-18C alkyl; R and R = 1-18C alkyl; K = cation; Z = CH2-CH2 or CH3-CH-CH2; and n = 1-50. An Independent claim is included for an aqueous polymer dispersion containing the above emulsifier mixture.

Abstract: An aqueous composition comprises a mixture of from 10 to 50% by weight of a polymer A) having a gel content of less than 40% by weight and a number-average molecular weight M n of the soluble fractions of less than 30,000 and from 50 to 90% by weight of a filler B), the amounts by weight being based on the weight sum of the polymer and of the filler.

Abstract: An aqueous composition is essentially free of organic solvents, plasticizers and additional tackifiers and contains water and 20-99% by weight of a polymer and 1-80% by weight of a filler, the percentages by weight being based on the sum of the components of the aqueous composition, with the exception of water.
