Versuchsvorschrift
The copolymer glycidyl methacrylate-ethylene dimethacrylate was prepared according to Example 1, with the distinction that the monomer mixture consisted of 70% of glycidyl methacrylate and 30% of ethylene dimethacrylate and that the mixture was agitated during polymerization more vigorously (700 r.p.m.). The fraction of particles with diameter of 15-20 μm was separated from the resulting product, thoroughly dried and modified in the following way: 5 g of the copolymer was dispersed in 20 ml of stearoyl chloride and shaken at 20° C. for 4 hours, at 70° C. for 1.5 hours, and at 80° C. for 6 hours. The product after stearoylation contained 5.60% of chlorine. The column 200×8 mm was packed with this sorbent and used for separation of the mixture of aromatic hydrocarbons (benzene, diphenyl, anthracene, chrysene, and benzopyrene) by the method of liquid chromatography.
