Claim 2:
3. A method for making an organoamino-functionalized oligosiloxane compound selected from the group consisting of Formulae A and B:, , the method comprising the steps of:
reacting a chlorinated cyclotrisiloxane of Formula (ii) or a chlorinated cyclotetrasiloxane compound of Formula (iv) with an organoamine or metal salt of an organoamine in the presence of a catalyst as shown in equations (2) or (4):, , wherein
R1 is selected from a linear C1 to C10 alkyl group, a branched C3 to C10 alkyl group, a C3 to C10 cyclic alkyl group, a C3 to C10 heterocyclic group, a C3 to C10 alkenyl group, a C3 to C10 alkynyl group, and a C4 to C10 aryl group;
R2 is selected from the group consisting of hydrogen, a C1 to C10 linear alkyl group, a branched C3 to C10 alkyl group, a C3 to C10 cyclic alkyl group, a C3 to C10 heterocyclic group, a C3 to C10 alkenyl group, a C3 to C10 alkynyl group, and a C4 to C10 aryl group, wherein R1 and R2 are either linked to form a cyclic ring structure or are not linked to form a cyclic ring structure; and
R3-9 are each independently selected from hydrogen, a linear C1 to C10 alkyl group, a branched C3 to C10 alkyl group, a C3 to C10 cyclic alkyl group, a C2 to C10 alkenyl group, a C2 to C10 alkynyl group, and a C4 to C10 aryl group, provided that R4, R6, and R8 are hydrogen.
