Synthetic example 1
[0246]
[0247] In a 100mL flask equipped with a stirrer, a thermometer, and a cooling tube, add 20.4g of the above-mentioned polysiloxane b solution and 0.205g of azabisisobutyronitrile, and stir at 80°C for 4 hours to obtain an acrylic polymer poly Silicone A solution.
[0248] The resulting acrylic polymerized polysiloxane A had a Mw of 7112 and an ADR of / Second.
Synthetic example 2
[0249]
[0250] Add 36.7g of 25% by mass TMAH aqueous solution, 600ml of IPA and 3.0g of water to a 2L flask equipped with a stirrer, a thermometer, and a cooling tube, then prepare 17g of methyltrimethoxysilane, 29.7g of phenyltrimethylsilane in a dropping funnel A mixed solution of oxysilane, 7.6 g of tetramethoxysilane, and 43.4 g of 3-(methacryloyloxy)propyltrimethoxysilane. The mixed solution was added dropwise at 40° C., and the mixture was stirred at the same temperature for 2 hours, and then neutralized by adding 10% aqueous HCl. 400 ml of toluene and 600 ml of water were added to the neutralized solution to separate into two layers, and the water layer was removed. The mixture was washed three times with 300 ml of water, the obtained organic layer was concentrated under reduced pressure to remove the solvent, and PGMEA was added to the concentrate so that the solid content concentration became 30% by mass to obtain a polysiloxane solution. Mw of the polysiloxane ob...

[0253]
[0254] Add 42.8g of 25% by mass TMAH aqueous solution, 600ml of IPA and 3.5g of water to a 2L flask equipped with a stirrer, a thermometer, and a cooling tube, then prepare 27.2g of methyltrimethoxysilane, 29.7g of phenyl A mixed solution of trimethoxysilane, 7.6 g of tetramethoxysilane, and 24.8 g of 3-(methacryloyloxy)propyltrimethoxysilane. The mixed solution was added dropwise at 40° C., and the mixture was stirred at the same temperature for 2 hours, and then neutralized by adding 10% aqueous HCl. 400 ml of toluene and 600 ml of water were added to the neutralized solution to separate into two layers, and the water layer was removed. The mixture was washed three times with 300 ml of water, the obtained organic layer was concentrated under reduced pressure to remove the solvent, and PGMEA was added to the concentrate so that the solid content concentration became 30% by mass to obtain a polysiloxane solution. The Mw of the polysiloxane obtained at this stage is...
