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.
