3. A method for preparing polyether-modified silicone oil
This method uses a platinum catalyst supported by porous ceramics to carry out a silylation reaction between a polyether with an olefinic group at the end and a hydrogen-containing silicone oil in a solvent. After the reaction, the filtrate is collected by filtration, and the solvent is removed from the filtrate to finally obtain a polyether-modified silicone oil.
