METHOD OF OBTAINING IODINE POLYSTYRENE Russian patent published in 2012 - IPC C08F8/18 C08F8/22

Abstract RU 2467018 C1

FIELD: chemistry.

SUBSTANCE: claimed invention relates to method of obtaining iodine polystyrene. Described is method of obtaining iodine polystyrene, lying in the following: molecular iodine is added to solution of polystyrene in chlorophorm, characterised by addition to reaction mixture of trifluoroacetic acid (TFAA) (in ratio 1:5 to chlorophorm), 40-45% water solution of peracetic acid (PAA) as oxidiser and keeping for 1.5 hours at 50-60°C.

EFFECT: reduction of process cost and increase of its environmental friendliness.
