  • Process for the preparation of optionally alkoxylated polyorganosiloxane resin by non-hydrolytic condensation
    Patent number: 5767216
    Abstract: The present invention relates to the synthesis of optionally alkoxylated polyorganosiloxane (POS) resins by non-hydrolytic condensation. The object is to provide a process which offers the possibility of controlling the crosslinking. This object, inter alia, is achieved by the process according to the invention, which makes provision for carrying out a non-hydrolytic condensation reaction between alkoxysilyl units (Mo1) and halogenosilyl units (Mo2), both of which are carried by identical or different silanes, in the presence of a catalyst of the Lewis acid type, said condensation reaction generating essentially .tbd.Si--O--Si.tbd. linkages and coproducts XR (X=halogen).
