Method for preparing polyorganosiloxanes (pos) by polycondensaton/redistribution of oligosiloxanes in the presence of a strong base and strong bases used |
| abstract |
The invention concerns the synthesis of silicone by anionic polymerisation of cyclic organosiloxane oligomers in the presence of a slightly nucleophilic strong base. The invention aims at providing novel strong base catalysts, more efficient in terms of solubility in the silicones, with hydrolysis stability strength and polymerising capacity. To achieve this, the invention provides for the use of ylides derived from aminophosphonium such as for example that of formula: [Me3N)3P-CHMe2]+, MeO or derived from phosphoranylidenes such as that of formula: [Me3P-HC=Pme3]+, t-BuO. The invention also concerns strong base catalysts as novel products. |
