Quaternary ammonium functional silicon compounds

A process for imparting antistatic properties to textile materials which comprises applying to the textile materials a composition obtained from the reaction of a carboxylic acid functional quaternary ammonium compound selected from the group consisting of compounds having the formulas ##STR17## with an aminofunctional silicon compound selected from the group consisting of

• (a) Silanes having the formula ##STR18## (b) Siloxanes having at least one unit of the formula ##STR19## (c) and mixtures thereof, at a temperature of from 0.degree. up to about 175.degree. C., in which R is a monovalent hydrocarbon radical having from 1 to 22 carbon atoms, R.sup.1 is a hydrocarbonoxy radical having the formula --(C.sub.n H.sub.2n O).sub.2, R.sup.2 is a divalent hydrocarbon radical selected from the group consisting of (CH.sub.2).sub.y, CH.dbd.CH and a cyclic divalent hydrocarbon radical selected from the group consisting of C.sub.6 H.sub.4, C.sub.6 H.sub.8, C.sub.6 H.sub.10, and C.sub.10 H.sub.6, R.sup.3 is a divalent hydrocarbon radical having from 2 to 10 carbon atoms, R.sup.4 is selected from the group consisting of a saturated divalent hydrocarbon radical having up to 10 carbon atoms, a divalent hydrocarbonoxy radical in which the oxygen is in the form of an ether linkage and an unsaturated divalent hydrocarbon radical having from 3 to 10 carbon atoms, X is an anionic radical, a is a number of from 1 to 4, b is 0, 1 or 2, c is 0, 1, 2 or 3, e is a number of from 1 to 3, f is a number of from 0 to 3, in which the sum of a+f cannot exceed 4, g is a number of from 0 to 2, in which the sum of e+g cannot exceed 3, n is 2, 3 or 4, r is a number of from 1 to 50 and y is a number of from 0 to 10 and thereafter heating the treated textile material at an elevated temperature.
