Producing amino-functional polysiloxane polymers, comprises reacting (a) optionally branched polysiloxanes having terminal hydroxy groups, (b) alkoxysilane compounds (I), and (c) water in presence of (D) at least one phosphorus-containing Bronsted acid compound. Producing amino-functional polysiloxane polymers, comprises reacting (a) optionally branched polysiloxanes having terminal hydroxy groups, (b) alkoxysilane compounds of formula ((R 1>) x(R 2>) 3 - xSiR 3>) (I), and (c) water in presence of (D) at least one phosphorus-containing Bronsted acid compound. R 1>1-4C alkyl, preferably CH 3(preferred) or ethyl; R 2>1-4C alkoxy, preferably OCH 3or ethoxy; R 3>organic group (contains at least one N); and x : 0-2, preferably 0-1. Independent claims are also included for: (1) a polysiloxane containing nitrogen-containing groups, produced by the above method; and (2) a composition comprising the above polysiloxane. |
