<p>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 <CHEM> wherein R<1> is a C1 to C50 divalent hydrocarbon radicals, each R<2> is hydrogen atom or a C1 to C50 monovalent hydrocarbon radicals, and R<3> is a C2 to C50 aliphatically unsaturated monovalent hydrocarbon radical. A method for the preparation thereof by a dehydration reaction of an amino-functional organosiloxane and an aliphatically unsaturated monocarboxylic acid is also described. <IMAGE></p> |
