FIELD: chemistry.
SUBSTANCE: invention relates to a copolymer rubber containing nitrile groups. Copolymer rubber includes α,β-ethylene unsaturated nitrile monomer units in the amount of 10-60 wt. % and diene monomer units and/or α-olefin monomer units in the amount of 40-90 wt. %. Copolymer rubber containing nitrile groups has an absolute weight-average molecular weight of 10,000–5,000,000 and a weight-average radius of inertia of 10–100 nm.
EFFECT: containing nitrile groups, copolymer rubber has improved flowability and improved technological characteristics and allows to obtain cross-linked rubber with improved typical physical properties.
