<p>Aqueous dispersions organopolysiloxanes which are free of organic transition metal compounds and of organic compounds of the metals of the main groups III, IV and V. These dispersions can be produced using the following starting compounds: (A) organopolysiloxane containing condensation-capable groups; (B) an organosilicon compound of the formula (II) {[(RO)3Si-R3-]e R21-e}aSi(OR)4-a, in which R can be identical or different and stands for a hydrogen atom or alkyl group with 1-6 carbon atoms, R2 can be identical or different and stands for SiC bonded hydrocarbon groups with 1-18 carbon atoms which are optionally substituted with halogen atoms, ether groups, ester groups, epoxy groups, mercapto groups, cyano groups or (poly)glycol groups, the latter being formed from oxyethylene- and/or oxypropylene units, and R3 can be identical or different and stands for bivalent hydrocarbon groups; a is 0 or 1, e is 0 or 1; and/or partial hydrolysates of the organosilicon compound with at most 8 Si-atoms; and (C) an organosilicon compound containing basic nitrogen.</p> |
