Abstract (en)
[origin: WO2005087842A1] The invention relates to a method for continuous production of aminofunctional siloxanes of general formula (III), (SiO4/2)k(R<1>SiO3/2)m(R<1>2SiO2/2)p(R<1>3SiO1/2)q [O1/2SiR<1>2-R-NH2]s [O1/2H]t (III), whereby organosiloxanes of general formula (IV) (SiO4/2)k(R<1>SiO3/2)m(R<1>2SiO2/2)p (R<1>3SiO1/2) q [O1/2H]r (IV), are reacted with cyclic silazanes of general formula (V), whereby the silazane of general formula (V) and the organosiloxane of general formula (IV) are continuously fed to a reactor, mixed therein, reacted together and then removed from the reactor zone. R, R<x>, R<1>, R<2>, e, s, t, r, k, m, p and q have the meanings given in claim 1.
