FIELD: polymer production.
SUBSTANCE: process of producing isoolefin copolymers in presence of zirconium halides or hafnium halides as initiator is characterized by that copolymerization is carried out in presence of organic nitro compounds of general formula R-NO2, wherein R represents C1-C18-alkyl, C3-C18-cycloalkyl, or C6-C24-cycloaryl.
EFFECT: enabled production of high-molecular weight isoolefin copolymers having insignificant content of gel.
