  • Method for preparing PolyOrganoSiloxanes (POS) by ring (S)—opening polymerization and/or POS redistribution in the presence of carbene (S) and POS compounds produced by said method
    Patent number: 7772350
    Abstract: A method for preparing polyorganosiloxanes (POS) by a ring-opening polymerization and/or linear, non-linear or cyclic POS redistribution in the presence of a nucleophilic carbene. The initial efficiency of the POS conversion is substantially increased at low temperature, resulting in less residual content of initial POS.
