摘要: The invention relates to an energy efficient, environmentally favourable process for the preparation of brominated butyl rubbers, that uses a bromination agent and a oxidizing agent in order to enhance the utilization of bromine contained in the bromination agent. In a preferred embodiment a common medium for both solution polymerization and subsequent bromination of the rubber is employed.
