Compounds of the formula <IMAGE> whereby, in the average molecule, 20 to 100% of the R1 radicals are <IMAGE> in which R2 is an alkylphenyl, dialkylphenyl or trialkylphenyl radical and the sum of the alkyl carbon atom per phenyl radical is 6 to 12, a=1 to 2; and 0 to 80% of the R1 radicals are <IMAGE> in which R3 is an alkyl radical with 1 to 16 carbon atoms, an organoacyl radical with 1 to 12 carbon atoms, or an aryl radical, b=1 to 2, c=1 to 30, and n=3 to 30, as well as melt spinning finishes comprising 5 to 100 weight percent of the compounds of claim 1, 0 to 90 weight percent of nonpolar or weakly polar oils, 0 to 30 weight percent of nonionic surfactants, 0 to 15 weight percent of ionic surfactants, and optional conventional additives, the sum of the components being 100 weight percent.
