摘要:
The invention relates to a process for preparing an amino-functional organosiloxane of the formula III, (SiO{fraction (4/2)})k(R1SiO{fraction (3/2)})m(R12SiO{fraction (2/2)})p(R13SiO½)q[O½SiR12—R—NH2]s[O½H]t (III) which comprises reacting an organosiloxane of the formula IV (SiO{fraction (4/2)})k(R1SiO{fraction (3/2)})m(R12SiO{fraction (2/2)})p(R13SiO½)q[O½H]r (IV) with a cyclic silazane of the formula V where R, Rx, R1, s, t, r, k, m, p and q are as defined in claim 1.
