Claims (1)

The method of obtaining rubber modifier by dispersing nitrogen-containing and oxygen-containing compounds in water, characterized in that polyethyleneimine with a degree of polymerization n = 2-90, or polyethylenepolyamine with a degree of polymerization n = 2-10, or polyhexamethyleneguanidine with degree of polymerization n = 2 is used as a nitrogen-containing compound -90, or its salts of general formula

where n = 2 - 90;
A ^- = H ₂ PO $\genfrac{}{}{0ex}{}{\text{-}}{\text{four}}$ ; NO $\genfrac{}{}{0ex}{}{\text{-}}{\text{3}}$ ; C ₁₇ H ₃₅ COO ^- ; HCO $\genfrac{}{}{0ex}{}{\text{-}}{\text{3}}$ ,
and polyglycols (polyethylene glycol or polypropylene glycol) of the general formula are used as the oxygen-containing compound.

where R ₁ = -OH; -C ₄ H ₉ ;
R ₂ = R ₃ = H, or R ₂ = R ₃ = -CH ₃ , or R ₂ = -H;
R ₃ = -CH ₃ ;
n + m = 2-120,
or hydroxybenzene derivative of general formula

where R ₁ = -CH ₃ ; -N;
R ₂ = -CH ₃ ; -N;
R ₃ = -CH ₃ ; -C ₂ H ₅ ; -H,
dispersion is carried out at a mass ratio of nitrogen-containing compounds, water and oxygen-containing compounds, equal to 1: (0.1-10.0): (0.05-0.5), followed by treatment with the reaction mass of the carrier — silicon dioxide, or kaolin, or zeolite, or lignin at a mass ratio of nitrogen-containing compounds, oxygen-containing compounds and media, equal to 1: (0.05-0.5): (1.0-30.0), and produce the resulting product.
