Embodiment 1
[0034] Preparation of glycidyl methacrylate and divinylbenzene copolymer (PDVB / GMA): add 200mL of 1% PVA aqueous solution to a 500mL three-necked flask equipped with a reflux condenser, a thermometer and a mechanical stirrer, raise the temperature to 45°C, and Add 19g DVB, 1g polar monomer GMA, toluene (mass is 160% of total monomer mass), n-heptane (mass is 40% of total monomer mass) and benzoyl peroxide (mass is mono 1.0% of the total body mass) of the mixed oil phase, adjust the stirring speed to 100r / min, and control the size of the oil droplets. Slowly raise the temperature to 75°C for 2 hours of polymerization; then raise the temperature to 85°C for 3 hours of polymerization; continue to raise the temperature to 95°C and boil the balls for 3 hours. The product was poured out, washed with hot water and cold water respectively, and extracted with petroleum ether for 24 hours to remove the porogen, and dried to obtain the precursor resin PDVB / GMA. The measured average pore...

[0038] Preparation of triallyl isocyanurate and divinylbenzene copolymer (PDVB / TAIC): add 200mL of 0.8% PVA aqueous solution to a 500mL three-necked flask equipped with a reflux condenser, a thermometer and a mechanical stirrer, and raise the temperature to 45 ℃, under stirring, add 19g DVB, 1g polar monomer TAIC, toluene (mass is 200% of the total monomer mass), n-heptane (mass is 50% of the total monomer mass) and azoisobutyronitrile ( The mass is 0.5% of the total mass of the monomer) mixed oil phase, and the stirring speed is adjusted to 120r / min to control the size of the oil droplets. Slowly raise the temperature to 70°C for 3 hours; then raise the temperature to 87°C for 4 hours; continue to raise the temperature to 90°C for 3 hours. The product was poured out, washed with hot water and cold water respectively, and extracted with petroleum ether for 24 hours to remove the porogen, and dried to obtain the precursor resin PDVB / TAIC. The measured average pore diameter of ...

[0043] Preparation of methyl acrylate and divinylbenzene copolymer (PDVB / MA): add 200mL of 1.2% PVA aqueous solution to a 500mL three-necked flask equipped with a reflux condenser, a thermometer and a mechanical stirrer, raise the temperature to 45°C, and stir Add 19g DVB, 1g polar monomer MA, toluene (the mass is 150% of the total mass of the monomer), n-heptane (the mass is 50% of the total mass of the monomer) and benzoyl peroxide (the mass is 150% of the total mass of the monomer) 0.5% of the total mass) of the mixed oil phase, adjust the stirring speed to 125r / min, and control the size of the oil droplets. Slowly raise the temperature to 68°C for 3 hours of polymerization; then raise the temperature to 83°C for 5 hours of polymerization; continue to raise the temperature to 95°C and boil the balls for 3 hours. The product was poured out, washed with hot water and cold water respectively, and extracted with petroleum ether for 24 hours to remove the porogen, and dried to o...
