FIELD: technological processes.
SUBSTANCE: present invention relates to a method of modifying butadiene-nitrile rubbers. This method involves combination of rubber and modifying agent. Modifying agent used is a mixture of oligodiene and chloroparaffin in weight ratio of 0.5:1.0 to 1.0:0.5. Amount of modifying agent is equal to 20-40 pts.wt. by 100 pts.wt. of the end product.
EFFECT: technologically simple method of modifying butadiene-nitrile rubber, which enables to obtain an end product with high frost- and oil-and-petrol resistance and long service life.
