A process for improving the end-use properties of tufted floor coverings, which comprises, in the manufacture of tufted floor coverings, mixing the dispersions or latexes which are necessary for the precoat and/or for the second coat, before their compounding, with a fluorosurfactant of the formula where Rf denotes a radical of the formula C.sub.6 F.sub.13, C.sub.8 F.sub.17, C.sub.10 F.sub.21 or C.sub.12 F.sub.25, R denotes a group of the formulae ##STR1## M and M' denote sodium, potassium or NH.sub.4 and n denotes a number from 4 to 8. The fluorosurfactant increases the tuft anchorage of the pile yarns and the adhesion of the backing.
The polymer of the present invention is derived from cyclic ether monomers, dioxane, dioxalane or trioxane and contains both pendant R.sub.f fluoro groups as well as polar groups. These polymers have good wetting, or flow, or leveling properties. They can be reacted with other monomers, such as in the preparation of polyesters, and can be used in waxes, polishes and coatings.
A fluorine containing polymer which acts as a wetting, flow or leveling agent, and has at least one polar group. The polymer has at least one pendant or ether side chain containing from about 1 to about 20 carbon atoms with at least 25% of the hydrogen atoms being replaced by fluorine atoms. The fluorinated polymers unexpectedly impart wetting, flow or leveling properties to a variety of coatings while producing little foam.
