FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing organometal oxane yttrium oxane aluminoxanes of general formula: [(R**O)_aMO]_k∙[Al(OR)_l(OR*)_x(OH)_zO_y]_m∙[(R**O)_sY(OH)_tO_r]_p, where k, p=0.1–6, m=3–12; a=2.3; k/m+1+x+2y+z=3; s+1+2r=3; M=Zr, Hf, Cr; R – C_nH_2n+1, n=2–4; R* – C(CH₃)=CHC(O)OC₂H₅; R** – C(CH₃)=CHC(O)CH₃. Method consists in that the organometal oxane yttrium oxane aluminoxanes are produced by reacting polyalkoxy aluminoxanes with the hydrate of yttrium acetylacetonate of formula {[CH₃(O)CCH=C(CH₃)O]₃Y⋅2.5H₂O} and refractory metal acetylacetonate [CH₃(O)CCH=C(CH₃)O]_bM, where b=3.4; M=Zr, Hf, Cr in an organic solvent at a temperature of 30–70 °C, followed by distilling off the solvent first at atmospheric pressure, and then under reduced pressure and at a temperature of up to 150 °C. Invention also relates to binders and impregnating compositions.

EFFECT: method of producing organometal oxane yttrium oxane aluminoxanes proposed.
