Embodiment 1
[0021] Add 40 g of distilled water to a three-necked flask equipped with a reflux condenser, and, under the condition of 70° C., stir nitrogen to remove oxygen. After 30 minutes, 10.0 g of styrene and 0.15 g of methacryloxypropyltrimethoxy silicon were mixed and added, then 0.070 g of initiator potassium persulfate was added, and 10 g of distilled water was added. The reaction was stirred for 2h. Suction filtration, drying to obtain a white solid polymer sample.
[0022] The polymer sample absorbed 5.1 g of benzene per gram at 2 minutes and 5.9 grams per gram of benzene at 2 hours.
Embodiment 2
[0024] Add 40 g of distilled water to a three-necked flask equipped with a reflux condenser, and, under the condition of 70° C., stir nitrogen to remove oxygen. After 30 minutes, 10.0 g of styrene and 0.35 g of methacryloxypropyltrimethoxy silicon were mixed and added, then 0.150 g of initiator potassium persulfate was added, and 10 g of distilled water was added. Reaction 2h. Suction filtration, drying to obtain a white solid polymer sample.
[0025] The polymer sample absorbed 6.3 grams of benzene per gram at 2 minutes and 12.9 grams per gram of benzene at 2 hours.
Embodiment 3
[0027] Add 50 g of distilled water into a three-necked flask equipped with a reflux condenser, and, at 70° C., stir and blow nitrogen to remove oxygen. After 30 minutes, 10 g of styrene and 0.37 g of methacryloxypropyltrimethoxy silicon were mixed and added, and 0.100 g of initiator potassium persulfate was added, followed by 10 g of distilled water. Reaction 2h. Suction filtration, drying to obtain a white solid polymer sample.
[0028] The polymer sample absorbs 7.2g of benzene per gram in 2 minutes, 14.3g per gram of benzene within 2 hours, and 11.5g per gram of benzene within 3 hours;
[0029] The polymer sample absorbs 8.3g of toluene per gram within 2 hours, and absorbs 11.4g of toluene per gram within 3 hours;
[0030] The polymer sample absorbs 13.2g of xylene per gram within 2 hours and 18.1g of xylene per gram within 3 hours;
[0031] The polymer sample absorbed 7.7 g of nitrobenzene per gram within 2 hours and 15.6 g per gram of nitrobenzene within 3 hours.
