| 摘要 |
The invention relates to a method for producing crosslinkable organopolysiloxane dispersions consisting in reacting at least one type of Si-bound alkoxy-or hydroxy-group-containing organopolysiloxane (1) with a highly reactive Si-bound alkoxy-or hydroxy group-containing silane (2) or the partial hydrolysate thereof and another group which enhances the reactivity of Si-alkoxy-or Si-acyloxy-groups in the silane (2) and makes it possible at least to double the starting viscosity of the (1) and (2) mixture for 2 hours at an ambient temperature (21°C) in the presence of a dispersion agent (3), preferably water, an emulgator (4) and optionally other substances (5) which do not participate directly in the reaction unless no metal-containing catalyst is used and the organopolysiloxanes in the obtained dispersions are crosslinked.
