FIELD: chemistry.
SUBSTANCE: composition contains the following, wt %: 0.05-6.9 (a) bisamide of saturated fatty acid with the structure: 
, where R1 and R2 are saturated hydrocarbyl groups with C11-C35; 0.14-7.6 (b) bisamide of unsaturated fatty acid with the structure: 
, where R3 and R4 are unsaturated hydrocarbyl groups with C11-C35; (c) dispersed cellulose material such as wood flour; (d) thermoplastic resin - flakes fractionated from molten high-density polyethylene (HDPE); (e) a finishing agent for finishing the cellulose material (c) with thermoplastic resin (d). The composition also contains an optional (f) inorganic dispersed material selected from pumice and talc and (g) a lubricant, separately or in a combination, selected from zinc stearate, sodium stearate, potassium stearate, paraffin wax or polyethylene wax.
EFFECT: invention enables to obtain composites with improved operational properties, ultimate bending strength and resistance to water absorption.
