Abstract
A process for preparing a cyclic polysiloxazane is disclosed. The cyclic polysiloxazane may optionally be converted to an a-alkoxy-ou-amino-functional polysiloxane. The cyclic polysiloxazane or the a-alkoxy-oo-amino-functional polysiloxane, may be used as a capping agent for a silanol-functional polyorganosiloxane in a process to make an amino-functional polyorganosiloxane.
