Zusammenfassung:	A method for preparing an amino-functional polydiorganosiloxane employs a removable catalyst. The method differs from previous methods in the selection of catalyst, order of addition of catalyst with respect to other starting materials, and catalyst removal. Un procédé de préparation d'un polydiorganosiloxane à fonction amino utilise un catalyseur amovible. Le procédé diffère des procédés précédents quant à la sélection de catalyseur, l'ordre d'ajout de catalyseur par rapport à d'autres matériaux de départ, et l'élimination de catalyseur.
