(FR) PROCÉDÉ DE PRÉPARATION DE SILOXANES À FONCTION OXAMIDE
(DE) VERFAHREN ZUR HERSTELLUNG VON OXAMID-FUNKTIONELLEN SILOXANEN
Abstract:
(EN) The invention relates to a process for producing oxamide-functional siloxanes by reacting (A) siloxanes of general formula (I), with (B) siloxanes selected from (B1) linear siloxanes of general formula HO [SiR2O] tH (II) and (B2) cyclic compounds of general formula (SiR4 2O)s (III), the groups and indices being defined as per claim 1, in the presence of (C) catalysts.
(FR) L'invention concerne un procédé de préparation de siloxanes à fonction oxamide par réaction de siloxanes (A) représentés par formule générale (I) avec des siloxanes (B) choisis parmi des siloxanes linéaires (B1) représentés par la formule générale HO [SiR2O] tH (II) et des composés cycliques (B2) représentés par la formule générale (SiR4 2O)s (III), les restes et les indices ayant la signification indiquée dans la revendication 1, en présence de catalyseurs (C).
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung von Oxamid-funktionellen Siloxanen durch Umsetzung von (A) Siloxanen der allgemeinen Formel (I), mit (B) Siloxanen ausgewählt aus (B1) linearen Siloxanen der allgemeinen Formel HO [SiR2O] tH (II) und (B2) cyclischen Verbindungen der allgemeinen Formel (SiR42O)s (III), wobei die Reste und Indizes die in Anspruch 1 angegebene Bedeutung haben, in Gegenwart von (C) Katalysatoren.
