FIELD: polymer production.
SUBSTANCE: invention relates to continuous method for halogenation of unsaturated elastomer dissolved in organic solvent. Continuous process involves (i) halogenation of elastomer via feeding halogenating agent into continuous elastomer solution stream and mixing elastomer solution with halogenating agent under turbulent motion conditions and (ii) at least one water washing and treatment with neutralizing solution. These operations are accomplished in one step with the aid of pumps. Water is also fed under turbulence conditions.
EFFECT: improved homogeneity and quality of product.
