摘要
FIELD: chemistry. ^ SUBSTANCE: invention refers to polymerisation techniques comprising diluents, including fluorohydrocarbons, and application thereof for production of new polymers essentially long-chain branching free. Produced is copolymer of isoolefine preferably of isobutylene, and that of multiolefine preferably of coupled diene, more preferably of isoprene essentially long-chain branching free. Copolymer has medium viscosity g1 exceeding or equal 0.978 as it is established with triple exclusion chromatography EXC. ^ EFFECT: improvement of rheological properties. ^ 31 cl, 6 dwg, 25 tbl, 151 ex
