Beschreibung
Zusammenfassung:	FIELD: chemistry of polymeric compounds. SUBSTANCE: sorbent synthesis is carried out by suspension copolymerization of 65 wt.-% divinylbenzene, 27.52 wt.-% ethylstyrene and 4.58 wt.-% glycidylmethacrylate in the presence of catalyst and carbon tetrachloride used at concentration 100-250% of monomer mass. Sorbent is used for sorption extraction of organic impurities from aqueous solutions and gaseous mixtures. EFFECT: improved method of sorbent preparing. 2 tbl Использование: сорбционное извлечение органических примесей из водных растворов и газовых смесей. Сущность изобретения: синтез сорбента суспензионной сополимеризацией 65 мас. % дивинилбензола, 27,52 мас.% этилстирола и 4,58 мас.% глицидилметакрилата в присутствии катализатора и четыреххлористого углерода, используемого в количестве 100 - 250% от массы мономеров. 2 табл.
