    • A reverse-phase suspension polymerisation process for the manufacture of polymer beads comprising forming aqueous monomer beads comprising an aqueous solution of water-soluble ethylenically unsaturated monomer or monomer blend and polymerising the monomer or monomer blend to form polymer beads while suspended in a non-aqueous liquid, and recovering polymer beads, in which the process comprises, providing in a vessel (1) a volume (2) of non-aqueous liquid wherein the volume of non-aqueous liquid extends between at least one polymer bead discharge point (3) and at least one monomer feed point (4), feeding the aqueous monomer or monomer blend through orifices (5) into, or onto, the non-aqueous liquid to form aqueous monomer beads, allowing the aqueous monomer beads to flow towards the polymer bead discharge point subjecting the aqueous monomer beads to polymerisation conditions to initiate polymerisation to form polymerising beads, wherein the polymerising beads have formed polymer beads when they reach the polymer bead discharge point, removing a suspension of the polymer beads in non-aqueous liquid from the vessel at the polymer bead discharge point and recovering water soluble or water swellable polymer beads from the suspension. The invention also relates to the apparatus suitable for carrying out a reverse-phase suspension polymerisation and polymer beads obtainable by the process or employing the apparatus.
    • 一种用于制备聚合物珠粒的反相悬浮聚合方法,其包括形成包含水溶性烯属不饱和单体或单体共混物的水溶液的含水单体珠粒,并将单体或单体共混物聚合以形成聚合物珠粒,同时悬浮在非水性 液体和回收的聚合物珠粒,其中该方法包括在容器(1)中提供非水性液体的体积(2),其中非水性液体的体积在至少一个聚合物珠粒排出点(3) 和至少一个单体进料点(4),通过孔口(5)将含水单体或单体共混物进料到非水性液体中或其上,以形成含水单体珠粒,使含水单体珠流向聚合物珠粒 排出点使含水单体珠粒聚合条件以引发聚合以形成聚合珠粒,其中聚合珠粒已形成聚合物珠粒 当它们到达聚合物珠粒排放点时,在聚合物珠粒排放点处从容器中除去聚合物小珠在非水性液体中的悬浮液,并从悬浮液中回收水溶性或水可溶胀聚合物珠粒。 本发明还涉及适用于进行反相悬浮聚合的装置和通过该方法或使用该装置可获得的聚合物珠。
