    Abstract: 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.
