FIELD: chemistry.
SUBSTANCE: invention relates to a method of halogenating polymers. The method involves contacting at least one polymer, having links derived from C4-C10 isoolefin, at least one halogen and at least one fluorohydrocarbon in a solution to obtain at least one halogenated polymer. The method involves the following steps: 1) suspension polymerisation using a diluent which contains at least one fluorohydrocarbon, with possibility of communication through a fluid medium with 2) a halogenation process to obtain at least one halogenated polymer.
EFFECT: improved method of halogenating polymers derived from C4-C10 isoolefins.
