METHOD OF OBTAINING POLYOXIME Russian patent published in 2015 - IPC C07C249/04 C07C251/32

Abstract RU 2571227 C1

FIELD: chemistry.

SUBSTANCE: described is method of obtaining polyoxime of general formula (-CH₂-CH₂-C(=NOH)-)_n with molecular weight from 1000 to 700000 g/mole by interaction of proper aliphatic polyketone with reagent - hydroxylamine source at atmospheric pressure in suspension mode, which is characterised by the fact that process is carried out in water medium.

EFFECT: high output of polyoxime, application of only water as solvent, simplification of technological process, reduction of wastes amount.
