    摘要： A process for halogenating polymers by contacting a polymer either in solution or in bulk with a halogenating agent in the presence of an acid scavenger. Halogenated polymer, e.g., butyl rubber, with a particular structure is obtained and the product suffers less molecular weight loss. Combinations of acid scavengers can also be used and the scavenger can be dispersed in the polymer prior to halogenation and/or added to the reaction zone during halogenation.

    摘要： A process for the continuous bromination of butyl rubber polymer by contacting the polymer with a brominating agent in a continuous flow device in which means are provided for disengaging reaction by-products and unreacted halogenating agents from the reaction mixture, by deforming and disrupting the brominated polymer surface and injecting a neutralizing agent into the polymer immediately after reaction thereby neutralizing the polymer, comprising contacting a polymer substantially free of acid scavengers, with the brominating agent at elevated temperatures the bromination reaction being carried out in an acid atmosphere, thereby producing a polymer having a substantial fraction of the bromine in the primary allylic position.

    摘要： Continuous halogenation of polymers is achieved by contacting polymer and halogenating agent in a continuous flow device in which the reactants are present as either co-continuous phases or wherein the halogenating agent is present as a continuous phase and the polymer is present as a discontinuous phase, the polymer is subjected to deformation during reaction and in which means are provided for disengaging reaction by-products and unreacted halogenating agent from the reaction mixture. In a preferred embodiment the polymer passes through three extruder-reactor zones under controlled conditions to achieve halogenation: feed, reaction (preferably vented), neutralization, and optionally a wash and exit zone. A continuous halogenating agent phase is achieved during reaction by avoiding complete filling of the reaction zone with polymer. Various halogenated polymers are produced, for example, halogenated linear low density polyethylene and halogenated butyl rubber.
