FIELD: chemistry of polymers. SUBSTANCE: method is carried out by mixing aromatic polycarbodiimide with coating binding polymer containing at least two carboxy groups, polycarbodiimide containing only aromatic carbodiimide groups is used. Also described are cross-linking agent, stabilized composition, substrate with cross linked polymer applied thereto, method of preparing aromatic polycarbodiimide and aromatic polycarbodiimide. EFFECT: new method is by 50 times slower than that known in the art resistance to scratching of the coating. 25 cl, 11 ex, 11 tbl |
