    摘要： A solution of butyl rubber in an inert solution such as n-hexane is halogenated in a continuous process using bromine chloride vapor and high intensity mixing means for both the halogenation and subsequent neutralization steps. Adjustment of the mole ratio of bromine chloride to isoprene, where an isobutylene-isoprene butyl copolymer is used, to less than about 1.5 to 1 prevents overhalogenation and significant molecular weight loss, while the use of bromine chloride vapor results in improved process safety.The doubly halogenated product, containing both bromine and chlorine in its structure can be vulcanized in the absence of sulfur, e.g., with zinc oxide. It is particularly useful in rubber compositions where the singly halogenated product is employed, but demonstrates product performance advantages compared to both brominated butyl rubber and chlorinated butyl rubber.

    摘要翻译： 丁基橡胶在惰性溶液如正己烷中的溶液在连续方法中被卤化，使用溴氯化物蒸气和用于卤化和随后的中和步骤的高强度混合装置。 使用异丁烯 - 异戊二烯丁基共聚物的氯化异丁烯与异戊二烯的摩尔比（其中使用异丁烯 - 异戊二烯丁基共聚物）的调节小于约1.5比1可以防止过度卤化和显着的分子量损失，而溴氯化物蒸汽的使用导致改进的工艺安全性。 在其结构中含有溴和氯的双卤代产物可以在不存在硫的情况下硫化，例如用氧化锌。 在使用单卤代产物的橡胶组合物中特别有用，但与溴化丁基橡胶和氯化丁基橡胶相比，它们具有优异的产品性能。

    摘要： A stabilized halogenated butyl rubber composition comprises halogenated butyl rubber, an alkali metal or alkaline earth metal carboxylate, an ether and an oxide or hydroxide of a Group IIA metal as exemplified by halogenated butyl rubber containing both bromine and chlorine stabilized with a composition comprising calcium stearate, polyethoxylated adducts of sorbitol esterified with from 1 to 6 moles of oleic acid and mixtures thereof, and calcium hydroxide.Halogenated butyl rubbers stabilized in the manner disclosed exhibit improved resistance to discoloration upon high temperature exposure, such as during the drying of polymers in the course of manufacture.

    摘要： Continuous halogenation of polymers is achieved in an extruder-reactor employing reactants, conditions and design features directed to maximizing mixing and contact of the polymer with the halogenating agent and neutralizing agent while simultaneously minimizing side reactions and polymer degradation. The polymer passes through three extruder-reactor zones under controlled conditions to achieve halogenation: feed, reaction, neutralization, and optionally a wash and exit zone. Various halogenated polymers are produced, for example, halogenated linear low density polyethylene and halogenated butyl rubber.

    摘要： In a process for the continuous halogenation of polymers by contacting polymer and halogenating agent in a continuous flow device in which the polymer and halogenating agent are subjected to deformation during reaction and in which means are provided for disengaging reaction by-products and unreacted halogenating agent from the reaction mixture, a significant process improvement is realized by injecting an inert gas into the halogenated polymers immediately after reaction in order to neutralize the product. In a preferred embodiment the process is carried out in an extruder-reactor and an optional, supplementary inert gas scrubbing zone is included. The process is amenable to saturated and unsaturated polymers.
