Embodiment 1-1
[0179] In a 100 mL three-necked flask, make 10.00 g of silicone intermediate 1 (hydrosilyl group-containing two-terminal methacryloyl silicone represented by formula (4)) and 0.2140 g of alkene-containing silicone represented by formula (5) The propyl phosphorylcholine compound was dissolved in 10.00 g of 2-propanol, heated to 80° C. using an oil bath, and then 40 μL of a 4% by weight hexachloroplatinic acid hexahydrate 2-propanol solution was added.
[0180] Dissolve 1.93 g of the allyl group-containing phosphorylcholine compound represented by the formula (5) in a solution of 5.78 g of 2-propanol to obtain a solution, add the solution to a 10 mL dropping funnel, and install In the upper part of the three-neck flask.
[0181] The solution in the dropping funnel was dropped over 30 minutes while maintaining 80°C. After the dropwise addition, the reaction was further carried out in a reflux state for 1 hour. After removing low-boiling point components by vacuum distillation, ...
