Abstract:
An aqueous composition comprising water and from 1 to 60% by weight of a polymer A) comprising polymerized units of(i) from 20 to 30% by weight of at least one vinylaromatic monomer having up to 20 carbon atoms, based on the total weight of A, (ii) from 45 to 75% by weight of at least one nonaromatic hydrocarbon having two conjugated double bonds, based on the total weight of A, (iii) from 0.1 to 20% by weight of at least one water-soluble monomer having a water solubility of at least 100 g per liter of water at 21Â° C. and 1 bar, said water-soluble monomer containing no acid group or acid anhydride group, based on the total weight of A, (iv) from 0.1 to 4.5% by weight of at least one monomer containing at least one acid group or acid anhydride group, based on the total weight of A, (v) from 0 to 30% by weight of at least one monomer other than (i) to (iv), based on the total weight of A, and from 40 to 99% by weight of at least one filler B), wherein weight % for A) and B) is based on the total weight of A) and B) and wherein component (iv) comprises itaconic acid and at least one monomer selected from the group consisting of acrylic acid, methacrylic acid, maleic acid and fumaric acid.
