    Abstract: The present invention relates to a process for preparing hydrophobically associating macromonomers M and to the novel macromonomers prepared by means of the process according to the invention. The macromonomers M comprise a copolymerizable, ethylenically unsaturated group and a polyether structure in block form, the latter consisting of a polyethyleneoxy block and a hydrophobic polyalkyleneoxy block consisting of alkyleneoxy units having at least 4 carbon atoms. Optionally, the macromonomers M may have a terminal polyethyleneoxy block. The macromonomers prepared by the process according to the invention are suitable for reaction with further monomers, especially with acrylamide, to give a water-soluble, hydrophobically associating copolymer.

    Abstract: The invention relates to a method for oil recovery, according to which an aqueous formulation comprising at least one water-soluble, hydrophobically associating copolymer is forced through at least one injection well into an oil deposit and crude oil is extracted from the oil deposit through at least one production well. The water-soluble, hydrophobically associating copolymer comprises at least acryl amide or derivatives thereof, a monomer having anionic groups and a monomer that can cause the association of the copolymer. The invention also relates to a water-soluble, hydrophobically associating copolymer with low shear degradation that is suitable for carrying out said method.

    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.
