Abstract
Aminopolysiloxanes of the following structure Q.sub.2 RSiO-- (SiR.sub.2 O).sub.x -(SiRR.sup.1 O).sub.y -SiRQ.sub.2 wherein R is a monovalent hydrocarbon group having 1 to 10 carbon atoms including alkyl, aryl and aralkyl groups; R.sup.1 is CH.sub.2 --CH.sub.2 --C--(CH.sub.3).sub.2 --CH.sub.2 --NHR.sup.2, R.sup.2 is hydrogen, an alkyl of C.sub.1 -C.sub.6, an alkyl amine of C.sub.1 -C.sub.6, or an alkanolamine of C.sub.1 -C.sub.6 ; Q is R, R.sup.1, hydroxyl, or an alkoxy of C.sub.1 -C.sub.4. x can be zero or integer; y is an integer, with x+y being less than 1,100, for use in various applications, including softening textiles.
