FIELD: chemistry of polymers. SUBSTANCE: described is adhesive composition comprises polyvinyl alcohol stabilized latex of butadiene polymer and donor compound of methylene group. Butadiene polymer latex is prepared by emulsion polymerization in the presence of polyvinyl alcohol, and donor compound from methylene group is selected from consisting of hexamethylene tetramine, paraformaldehyde, sym-trioxane, anhydroformaldehyde aniline, ethylenediamine formaldehyde, methylol derivatives of urea and formaldehyde, acetaldehyde, furfural, methylphenol compounds, (1) acetal copolymers, (3) gamma- polyoxymethylene ethers having typical structure R10O-(CH2O)n-R11 and polyoxymethylene glycols having typical structure HO-(R12O)x-(CH2O)n-(R13O)x-H wherein R10 and R11 are ether identical or different, and each is alkyl group containing from 1 to 8 carbon atoms; R12 and R13 are identical or different, and each is alkylene group containing from 2 to 12 carbon atoms; n is more than 100; and x is within 0 to 8, provided that at least one of x is at least 1. Polyvinyl alcohol stabilized latex of butadiene polymer and donor compound of methylene in combination five densely cross linked strong film which provides for excellent adhesiveness and resistance to environment conditions. EFFECT: improved properties of the aqueous adhesive. 15 cl, 8 ex, 5 tbl
