    • Continuous process for preparing a halogenated polymer comprising a step of polymerization of at least one halogenated monomer in a medium comprising carbon dioxide in the liquid or supercritical state (L/SC-CO2), in at least one pressurized reactor, said process comprising at least: - (1) an expansion of the suspension resulting from the reactor; - (2) a separation of the expanded suspension resulting from the reactor into a first stream, containing the solid phase comprising the halogenated polymer and into a liquid, gaseous or supercritical second stream, which is a mixture of CO2 and of monomer not converted to polymer; and the recovery of this first stream and of this second stream; - (3) an optional reheating, applied to the expanded suspension, before or after its separation into first and second streams, with optional recovery of the cold energy generated by the expansion; - (4) a recompression of the second stream and the optional cooling thereof in order to recycle it to the reactor feed, with a fresh monomer make-up and, possibly, a CO2 make-up; - a final step (5) of degassing the halogenated polymer, combined with a continuous technique of forming the polymer into granules. Device for implementing the process.
    • 用于制备卤化聚合物的连续方法,其包括在至少一个加压反应器中在包含液态或超临界态(L / SC-CO2)的二氧化碳的介质中聚合至少一种卤代单体的步骤,所述方法至少包括 :(1)由反应器产生的悬浮液的膨胀; - (2)将由反应器产生的膨胀悬浮液分离成含有含卤化聚合物的固相的第一物流和分离成液体,气体或超临界第二物流,该第二物流是CO2和未转化成单体的混合物 聚合物; 并回收这第一股流和这第二股流; - (3)在分离成第一和第二物流之前或之后,对膨胀的悬浮液进行任选的再加热,同时可任意回收由膨胀产生的冷能; - (4)第二物流的再压缩和其任选的冷却以将其再循环到反应器进料中,其中新鲜的单体构成和可能的CO 2构成; - 脱卤卤化聚合物的最后一步(5),以及将聚合物形成颗粒的连续技术。 实施过程的设备。
