Versuchsvorschrift

A 300-mL roundbottomed flask, equipped with a distillation head and a mechanical stirrer, is utilized. 200 mL of water containing 0.5 g of potassium persulfate, 0.5 g of trisodium phosphate dodecahydrate, and 1.5 g of sodium dodecyl sulfate are heated to 70° C. under a nitrogen atmosphere. A seed emulsion is formed by adding 4.5 mL of styrene and 0.5 mL of ethylene glycol dimethacrylate. After 30 min the seed emulsion has a particle size of 0.021 μm and pH of 8.5. A solution of 20 g of vinyl carbazole and one gram of "Aerosol" OT-100 in 10 mL of dichloromethane is then added at a rate of 0.1 mL/min. The dichloromethane is removed by distillation as soon as it is added. After the core emulsion is complete, 0.1 g of potassium persulfate in 10 mL of water is added, and then 2.5 mL of glycidyl methacrylate is added at a feed rate of 0.1 mL/min. 45 min is allowed for the polymerization. The final particle size is 0.041 μm. The final solids content is 10.5%.
