Process for reducing the fouling of a surface O, wherein an aqueous solution S of at least one polymer P comprising styrene and at least one ester E of (meth)acrylic acid and polyethylene oxide in a molar ratio of 0.05:1 to 50:1 is applied to said surface O.

Processes for reducing the fouling of surfaces

A reverse-phase suspension polymerisation process for the manufacture of polymer beads comprising forming aqueous monomer beads of an aqueous solution comprising 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, recovering polymer beads, and then cleaning the non-aqueous liquid in which the process comprises providing the non-aqueous liquid in a vessel (), forming a suspension of monomer beads from the aqueous monomer or monomer blend in the non-aqueous liquid, initiating polymerisation to form polymerising beads, removing a suspension of the polymer beads in non-aqueous liquid from the vessel and recovering, water soluble or water swellable polymer beads from the suspension, in which the non-aqueous liquid contains impurities which comprise particles, and then transferring the non-aqueous liquid from the suspension to a cleaning stage, in which the cleaning stage provides a cleaned non-aqueous liquid suitable for use in a reverse-phase suspension polymerisation process, which cleaning stage comprises removing particles from the non-aqueous liquid in at least one filtration step. 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. The invention further relates to a cleaned non-aqueous liquid obtainable by the process.

Reverse-phase polymerisation process

The invention relates to a process for working-up a reaction mixture () comprising polyetherol and dissolved alkali metal comprising catalyst, wherein at least alkali metal ions of the dissolved alkali metal comprising catalyst are partially or completely removed from the mixture by a membrane separation process, the process comprising following steps:
