FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing peroxide-curable halogenbutyl ionomers with high content of multi-olefin. The method of producing a halogenbutyl ionomer with high content of multi-olefin involves polymerisation of a mixture of monomers containing 80-95 wt % isobutene monomer and 4-20 wt % isoprene monomer in the presence of AlCl3 and a source of protons and/or carbocationic compound or silyl cationic compound, capable of initiating polymerisation and 0.01-1.0 wt % multi-olefin cross-linking agent, halogenation of the butyl polymer and reaction with a phosphorus-base nucleophile.
EFFECT: obtaining halogenbutyl ionomer with high content of multi-olefin ranging from approximately 2 to 10 moles %.
