Patent ID: 7112626

Claim:
A method of adhering a floor covering, comprising: applying an aqueous composition to said floor covering; and installing the floor covering, wherein said aqueous composition comprises: A) 10 to 50% by weight of a polymer having a gel content of 5 to 40% by weight and a number-average molecular weight, Mn, of a tetrahydrofuran-soluble fraction of less than 30,000, where said polymer comprises from 60 to 100% by weight of a C 1 - to C 20 -alkyl (meth)acrylate or mixture of at least two C 1 - to C 20 -alkyl (meth)acrylates, based on a total weight of said polymer, and B) 50 to 90% by weight of a filler; wherein the amount of said polymer and the amount of said filler are based on the weight sum of the polymer and of the filler; wherein said filler is selected from the group consisting of a chalk having an average particle diameter of from 2 to 50 μm, a quartz flour having an average particle diameter of from 3 to 50 μm and a combination thereof; and wherein said polymer optionally further comprises a monomer unit selected from the group consisting of a C 1 –C 10 -hydroxyalkyl (meth)acrylate, a (meth)acrylamide and its N—C 1 –C 4 -alkyl-substituted derivative, an ethylenically unsaturated carboxylic acid, a dicarboxylic acid, a monoester of a dicarboxylic acid and an anhydride of a dicarboxylic acid.
