UNSATURATED POLYOXIM AND METHOD OF ITS PRODUCTION Russian patent published in 2009 - IPC C08G73/00 C07C249/08 

FIELD: chemistry.

SUBSTANCE: invention relates to new organic polymers, in particular, to unsaturated polyoxims which can be used for producing polyamines, polyamides, chelating agents and other chemical products and can form a basis for preparation of medical products, antioxidants, pigments, hermetics and catalysts. The invention proposes an unsaturated polyoxims of the general formula: [-CH₂)_a-(R)C(R₁)-]_m-[-(CH₂)_b-CH(R₂)-C(=NOH)-CH(R₃)-(CH₂)_c-]_n-[-(CH₂)_b-CH(R₂)-C(=O)-CH(R₃)-(CH₂)_c-]_p-[-CH₂-C(R₂)=C(R₃)-CH₂-]_q, where m=0-547, n=2-19, p = 0-17, q = 1-680; R, R₁, R₂, R₃ are hydrogen, halogen, alkyl, phenyl or cyanic group, while a, b and c are integers from 0 to 3. The invention comprises also the method of producing the aforesaid unsaturated polyoxims consisting in interaction of unsaturated polymer with nitrogen protoxide at 50 to 350°C and nitrogen protoxide of 0.01 to 100 atm in organic solvent with subsequent processing by hydroxylamine at 10 to 90°C and atmospheric pressure in organic solvent or in heterophase system "organic solvent-water".

EFFECT: production of new unsaturated polyoxims with controlled three types of groups, ie oxym, carbonyl and dual bond C=C, expanding their applications.
