preparation Embodiment 1

[0039] Preparation Example 1: Preparation of 1-(2-methoxyethoxy)-4-vinylbenzene

[0040] 1) Preparation of hydroxystyrene

[0041] The sodium hydroxide of 0.275 mole is put into the round bottom flask of 500ml, the dehydrated alcohol of 60ml is added wherein to dissolve sodium hydroxide, then the acetoxystyrene of 0.065 mole is added in the flask, under nitrogen atmosphere will obtain The solution was stirred at room temperature for 4 hours. Next, 50 ml of distilled water and 30 ml of ethyl acetate were sequentially added to the resulting mixture to extract an organic layer, and the extraction process of the organic layer was repeated three times. The extracted organic layer was dried over anhydrous magnesium sulfate and filtered to remove any remaining moisture. Thereafter, the solvent was removed under reduced pressure to obtain 7.54 g (yield: 96%) of hydroxystyrene as a yellow solid. Purified hydroxystyrene 1 H nuclear magnetic resonance (NMR) spectral data are as follo...

Next, 50 ml of distilled water and 30 ml of ethyl acetate were sequentially added to the resulting mixture to extract an organic layer, and the organic layer extraction process was repeated three times. The extracted organic layer was dried using anhydrous magnesium sulfate and filtered to remove residual moisture. Thereafter, the solvent was removed under reduced pressure to obtain 7.54 g (yield: 96%) of hydroxystyrene as a yellow solid. Purified hydroxystyrene 1 H NMR spectral data are as follows:

Embodiment 1

[0055] Embodiment 1: the preparation of modified styrene polymer

[0056] 28.8 millimoles of styrene and 1.4 millimoles of the styrene compound prepared according to Preparation Example 2 were put into a 100 ml Schlenk flask, 30 ml of anhydrous n-hexane was added thereto, and then the temperature inside the flask was raised to 40°C. When the temperature inside the reactor reached 40° C., 0.25 ml (0.63 mmol in hexane) of a 2.5 M n-butyllithium hexane solution was added to the reactor to cause an adiabatic heating reaction. After about 20 minutes, methanol was used to terminate the polymerization reaction to complete the preparation of the modified styrene polymer.
