ABSTRACT:
Concentrated, aqueous, colloidal dispersions of tetrafluoroethylene polymers having a polymer solids content of 25 to 70% by weight, which comprise, as the dispersion stabilizer, an amine oxide of the formula ##STR1## in which R.sup.1 is an alkyl radical having 6 to 22 carbon atoms or a mixture of such alkyl radicals and R.sup.2 is an alkyl radical having 1 to 22 carbon atoms or a mixture of such alkyl radicals, and in which R.sup.1 and R.sup.2 are identical or different and 50 to 0% by weight of the alkyl radicals R.sup.1 and R.sup.2 can be replaced by alkenyl radicals having 6 to 22 carbon atoms and having 1 to 3 C.dbd.C double bonds, are obtained by concentration with addition of these dispersion stabilizers. The dispersions are used for impregnating yarns and textile sheet-like structures.
