FIELD: polymer production. ^ SUBSTANCE: process comprises feeding halogenating agent into continuous stream of elastomer solution, mixing the two components, which, after interaction, produce halogenated elastomer. The latter is neutralized by means of a neutralization medium and at least once washed with a washing medium. Neutralization and washing are carried out in reactor provided with static and dynamic means creating turbulent motion including inversion effect and consecutive withdrawal of excess of halogenating agent and settling separation of washing and neutralization media from halogenated elastomer. Process is carried out in installation comprising halogenation, washing, and neutralization reactors. ^ EFFECT: intensified all process stages, reduced equipment dimensions, and enabled continuous process resulting in production of homogeneous high-quality product. ^ 19 cl, 5 dwg, 1 tbl, 8 ex |
