Clear liquid with ammonia odor | [Uses]
1,1,3,3-Tetramethyl-1,3-divinyldisilazane is used for silicone rubber, silicone resin, silicone gel and vinyl manufacturing. | [Application]
1,1,3,3-Tetramethyl-1,3-divinyldisilazane, a vinylsilazane, could cross-linked with polyhydromethylsiloxane in the presence of Karstedt's catalyst. When the reactions were carried out in solvent-free conditions, non-porous polysiloxane-silazane networks were obtained[1].
| [Flammability and Explosibility]
Flammable | [Synthesis]
Add 2 mol of dimethyl vinyl chlorsilane to the reactor, pass ammonia into it for the reaction, the amount of ammonia is controlled to be the molar ratio of dimethyl vinyl chlorsilane to ammonia 2:3.4, and 99% of the ammonia is passed in 2 hours, | [Toxics Screening Level]
The initial threshold screening level (ITSL) for tetramethyldivinyldisilzane (CASRN 7691-02-3) is 30 μg/m3 based on an annual averaging time. | [References]
