Flammfeste, wäßrige Polymerzubereitungen

摘要

An aqueous formulation comprises a polymer constructed of from 0 to 99.95% by weight of one or more principal monomers I selected from C 1 -C 20 -alkyl (meth)acrylates, aromatic vinyl compounds having up to 20 carbon atoms, vinyl esters of carboxylic acids containing up to 20 carbon atoms, ethylenically unsaturated nitriles, vinyl ethers of alcohols containing from 1 to 10 carbon atoms and aliphatic hydrocarbons having from 2 to 8 carbon atoms and 1 or 2 double bonds, from 0.05 to 100% by weight of one or more monomers II which carry at least one functional group, which is not to be understood as meaning an ethylenically unsaturated group, this functional group being reactive with the below-defined phosphorus compound in such a way that the phosphorus compound becomes thereby bonded to the polymer, and from 0 to 80% by weight of one or more further monomers III which differ from monomers I and II, and a phosphorus compound which is reactive with the functional group of monomer II, the phosphorus compound being or becoming bonded to the polymer via the functional group. The formulation can be used for consolidating fibrous materials, in particular fibrous webs, or in coatings, impregnants, cleaning or care agents or adhesives to provide flame proofing.
