| titleOfInvention | Method for the production of polymethylvinylsiloxane resins with recycling of volatile oligoorganosiloxanes |
| abstract | The invention relates to the field of silicon resins, particularly polymethylvinylsiloxane resins. The invention more specifically relates to a method for the production of polymethylvinylsiloxane resins comprising at least two different types of siloxy motifs R 3 SiO 1/2 (motif M) and SiO 4/2 (motif Q, optionally Q OH ), said method comprising the following steps: a) producing a siloxane resin comprising motifs Q by acidic hydrolysis of a siloxane resin precursor, preferably an alkaline silicate; b) functionalizing the siloxane resin obtained in step a) with halogenosilanes in the presence of an apolar solvent, the functionalizing generating sub-products including volatile oligosiloxanes (silox); c) recovering silox produced in step b) in a solution in the apolar solvent; and d) subjecting the resin functionalized in step b) to rearrangement with the aid of a strong base in order to eliminate the silanols, wherein at least a part of the silox produced during step b) and recovered in step c) is recycled. |
