Abstract:
1. A composition comprising a dispersion of at least one (meth)acrylate polymer A) and at least one (meth)acrylate polymer B) in water, wherein: for every 100 parts by weight of the (meth)acrylate polymer A) there is from 1-400 parts by weight of the (meth)acrylate polymer B); the (meth)acrylate polymer B) comprises at least one compound of formula (I) copolymerized and different from the (meth)acrylate polymer A); the polymers A) and B) are obtained by emulsion polymerization of a mixture comprising: a) from 0.1 to 99.9 percent by weight of the at least one compound of formula (I); wherein: R R R wherein: R n is a whole number of from zero to two hundred; and o and p, independently of one another, are a whole number of from zero to two, wherein R R R m is a whole number of from one to five; and R and b) from 99.9 to 0.1% by weight of at least one ethylenically unsaturated monomer, which differs from, and is copolymerizable with, the at least one compound of formula (I), wherein: the at least one compound of formula (I) and the at least one ethylenically unsaturated monomer together give 100% by weight of polymerizable constituents of the mixture; and the parts by weight of the (meth)acrylate polymer A) and the (meth)acrylate polymer B) are based on a solids content of the (meth)acrylate polymers A) or B) in the dispersion.
