Synthesis

Cool down 600g H2O to below 5°C, slowly add the intermediate product 3-(chlorodimethylsilyl)propyl methacrylate, restore room temperature and stir for 8h. Then stand, separate the organic phase, wash with water to neutral, add anhydrous sodium sulfate to dry the organic phase, filter to remove the desiccant, and remove the low boiling point substance in the system under reduced pressure to obtain 645.11g of product 1,3-Bis(3-methacryloxypropyl)tetramethyldisiloxane, with a yield of 97%.
