Embodiment 1
[0030] After mixing and stirring 20 parts of dodecyl acrylate, 20 parts of methyl methacrylate, 16 parts of styrene, and 7.5 parts of hydroxyethyl acrylate, 32 parts of ethyl acetate and 1 part of initiator were added, and the mixture was fully stirred and dissolved to obtain a mixture;
[0031] The above mixture is divided into two parts of equal quality, one part is placed in a three-diameter flask, one part is placed in a constant pressure dropping funnel, and nitrogen is passed into the three-necked flask to remove the oxygen in the bottle, and the stirring speed is controlled as 300rmp, heat the three-diameter flask to 75°C for the reaction, after 5 hours of reaction, control the liquid in the constant pressure dropping funnel to drop into the three-diameter flask at a constant temperature of 75°C for 2h, and then keep the reaction at 75°C for 3h. Naturally cooled to room temperature, and the solvent was evaporated under reduced pressure to obtain an oil-absorbing swollen ...
