AQUEOUS DISPERSIONS OF PRE-CROSSLINKED ORGANOPOLYSILOXANES

An aqueous of pre-crosslinked organopolysiloxanes and process for producing the same. The aqueous dispersion is preferably aqueous emulsion, including pre-crosslinked organopolysiloxanes which contains on average at least one structural unit of the general formula SiRO2/2-Y-SiRO2/2 and units of the...

Beschreibung
Zusammenfassung:	An aqueous of pre-crosslinked organopolysiloxanes and process for producing the same. The aqueous dispersion is preferably aqueous emulsion, including pre-crosslinked organopolysiloxanes which contains on average at least one structural unit of the general formula SiRO2/2-Y-SiRO2/2 and units of the formula R2SiO2/2. Where Y is a radical of the formula-R2-[NR3-R4-]x-NR3-OC-[C(Z1)(H)]k1-[C(Z2)(H)]k2-CO-NR3-[R4-NR]x-R2and where R, R2, R3, R4, k1, k2, x, Z1 and Z2 have a definition a set forth within herein. Additionally, the sum of k1+k2 is ≥1, the that at least one radical Z1 or Z2 is a hydroxyl or NHR3 group, preferably a hydroxyl group, and so the bridging group Y contains at least one hydroxyl or NHR3 group, preferably at least one hydroxyl group.
