ABSTRACT:
Imidazolinyl-functional organosiloxanes in which an aliphatically unsaturated monovalent hydrocarbon radical is bonded at the 2-position of the imidazoline ring, have from 2 to 1,100 siloxane units where at least one siloxane unit has an imidazolinyl radical of the following general formula bonded to silicon ##STR1## wherein R.sup.1 is a C.sub.1 to C.sub.50 divalent hydrocarbon radical, each R.sup.2 is hydrogen atom or a C.sub.1 to C.sub.50 monovalent hydrocarbon radicals, and R.sup.3 is a C.sub.2 to C.sub.50 aliphatically unsaturated monovalent hydrocarbon radical, and method for the preparation thereof by a dehydration reaction of an amino-functional organosiloxane and an aliphatically unsaturated monocarboxylic acid.
