ABSTRACT:
Silicone polyether copolymers having the general formula ##STR1## wherein R is a radical selected from the group consisting of ##STR2## in which the radical R is linked to the polyether through an ester linkage, 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 silicone containing monovalent or divalent radical selected from the group consisting of ##STR3## R.sup.2 is selected from the group consisting of saturated divalent hydrocarbon radicals, hydrocarbonoxy radicals in which the hydrocarbon group is linked to the silicon by a carbon bond and the oxygen is in the form of an ether linkage, and unsaturated divalent hydrocarbon radicals, R.sup.3 is selected from the group consisting of monovalent hydrocarbon radicals having from 1 to 18 carbon atoms, alkoxy radicals having from 1 to 18 carbon atoms and OSi(R.sup.4).sub.3 radicals, R.sup.4 is a monovalent hydrocarbon radical having from 1 to 18 carbon atoms, R.sup.5 is a monovalent radical selected from the group consisting of O.sub.0.5 SI(R.sup.4).sub.3 and O.sub.0.5 R.sup.4, where R.sup.4 is the same as above, and when R is cationic, then A must be anionic 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 at least 1 when A is a monovalent radical and when A is a divalent radical the sum of b, c and d must be at least 0.5 and up to 3 with the proviso that when c is greater than 0 then a must be at least 1, e is a number of from 1 to 200, m is a number of from 1 to 20,000, n is 2, 3 or 4, x is a number of from 1 and up to 400, preferably from 10 to 250 and y is a number of from 0 to 8. These silicone polyether copolymers may be used alone or in combination with other textile treating agents to impart oleophobic and hydrophobic properties thereto.
