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.
