FIELD: production of polyurethane composition. SUBSTANCE: proposed polyurethane composition contains (mass parts): polyethylene butylene glycol adipinate 86.4-72, diisocyanate 9-10, derivatives of dimethylaminomethyl phenol 0.3-1.2, polyurethane wastes on the base of polyesters 4.6-18, benzoyl chloride 0.1-1.0. Mentioned above derivatives of dimethylaminomethyl phenol are used as catalyst. EFFECT: improves viability of composition and its physical and mechanical features. |
