| titleOfInvention | Process for producing POS by ring-opening polymerization and / or redistribution of polyorganosiloxane (POS) in the presence of carbene and POS compound produced by the process |
| abstract | The present invention relates to a process for producing POS by ring-opening and / or redistribution polymerization of linear, non-linear or cyclic polyorganosiloxane (POS) in the presence of nucleophilic carbene. The object of the present invention is to provide an improved process for the production of POS by means of an effective catalyst system at low temperatures. In this case, the conversion efficiency of the initial POS (eg D4) is substantially increased compared to the prior art in such a way that the residual content of the initial POS (eg D4) is less than before. For this purpose, the following ingredients are used: 500 g POS and / or POScy (ie D4), 0-10 g, preferably 0.5-2 g chain terminator (ie M2), 0-10 g, preferably Is 0.01 to 1 g of carbene salt precursor (formula (III) or (III ′), ie imidazolium salt), 0 to 10 g, preferably 0.01 to 0.5 g of base (ie t-BuOK) As well as 0.1-10 mL of solvent (ie THF). |
