ABSTRACT:
Silylated polyethers having the general formula: ##STR1## wherein at least one R is selected from the group consisting of an --NH radical, an ammonium radical or a radical of the formula ##STR2## in which the radicals are linked to the polyether through an ester, amine, amide or ammonium radical and the remaining R groups are selected from hydrocarbonoxy radicals having up to 18 carbon atoms, hydroxyl radicals or a radical of the formula ##STR3## R.sup.1 is a divalent hydrocarbon radical selected from the group consisting of --(CH.sub.2).sub.y, --CH.dbd.CH--, or a cyclic radical selected from the group consisting of C.sub.6 H.sub.4, C.sub.6 H.sub.8 and C.sub.10 H.sub.6 ; A is a silicon containing radical selected from the group consisting of cationic or anionic radicals of the formula or ##EQU1## and nonionic radicals of the formula ##EQU2## wherein R.sup.2 and R.sup.3 which may be the same or different, are monovalent hydrocarbon radicals having from 1 to 18 carbon atoms, R.sup.4 is an ionic radical linked to a silicon atom consisting of hydrogen, carbon, oxygen and nitrogen atoms selected from the formulas ##STR4## in which R.sup.5 is a nonionic radical consisting of carbon, hydrogen, oxygen and nitrogen atoms selected from the formulas ##STR5## and when R is an --NH radical, then R.sup.5 may be a divalent hydrocarbon radical and R.sup.6 is a radical having from 1 to 10 carbon atoms selected from the group consisting of a saturated divalent hydrocarbon radical, a divalent hydrocarbonoxy radical in which the oxygen is in the form of an ether linkage and an unsaturated divalent hydrocarbon radical in which the unsatisfied valences are linked to a silicon atom, and when R is cationic, then A must be anionic, and when R is anionic, then A must be cationic and when R is nonionic then A must be nonionic, a is a number of from 0 to 4, b, c and d are each numbers of from 0 to 1, the sum of b, c and d must be 1 when A is a monovalent radical and 0.5 when A is a divalent radical and when b, c or d are O, then R must be a hydroxyl or hydrocarbonoxy radical or a radical of the formula ##STR6## e is a number of from O to 2, n is 2, 3 or 4, x is a number of at least 1 and up to 600, preferably from 10 to 250 and y is a number of from 0 to 8. These silylated polyethers may be used to treat textile materials to impart hydrophilic finishes thereon.
