The present invention is directed to the use of a quaternized derivative of polyisobutylene as stabiliser in inverse emulsions like inverse emulsions used for a reverse-phase emulsion polymerisation process, e.g. for the polymerisation of acrylamide and ethylenically unsaturated cationic monomers. Such emulsions are e.g. used as flocculant for waste water treatment. The present invention is further directed to inverse emulsions comprising a quaternized derivative of polyisobutylene. The inverse emulsions have sufficiently low viscosity and sufficiently high shear stability. The present invention is further directed to an inverse emulsion polymerisation process, wherein the inverse emulsion comprises a quaternized derivative of polyisobutylene.

Stabilisers for use in inverse emulsion polymerisation processes

The present invention relates to coated polymer particles comprising a water-swellable polymer core and an essentially continuous coating encapsulating the core. The coating comprises an oxide, hydroxide or oxide hydrate of silicon, aluminum, zirconium, tin or titanium. The polymer particles do not show instantaneous swelling, when contacted with water or a water-containing liquid, but show delayed water absorption after an appropriate period of time. The coated polymer particles may be used in oil fields, in mining, for construction chemical compositions or as carrier for active substances. The coated polymer particles are prepared by a suspension coating process or a fluidized bed coating process.

This formulation can also comprise a cement, and also additives for foam stabilization, shrinkage reduction, flexibilization, hydrophobization, or dispersion, fibres and fillers or a mixture thereof, and can be a single-component or two-component formulation. An incombustible, sound-absorbing, thermally insulating geopolymer foam element.

A geopolymer foam formulation, comprising at least one inorganic binder selected from the group consisting of latently hydraulic binders, pozzolanic binders and mixtures thereof; at least one alkaline activator selected from the group consisting of alkali metal hydroxides, alkali metal carbonates, alkali metal aluminates, alkali metal silicates and mixtures thereof; at least one surfactant selected from the group consisting of anionic surfactants, cationic surfactants, non-ionic surfactants and mixtures thereof; a gas phase and water. This formulation can also comprise a cement, and also additives for foam stabilization, shrinkage reduction, flexibilization, hydrophobization, or dispersion, fibers and fillers or a mixture thereof, and can be a single-component or two-component formulation. Also, a process for the production of this formulation via foaming by mechanical introduction of air, the use of the formulation for the production of an incombustible, sound-absorbing, thermally insulating geopolymer foam element and the geopolymer foam element.

A dry mortar mixture based on at least one hydraulic and/or latently hydraulic binder which in the made-up and not yet cured state has firm properties is claimed. The novel dry mortar mixture is characterized in that it contains at least one representative of a dispersant and at least one compound having superabsorbent properties. This mixture makes it possible to carry over the advantages of known tile adhesives for horizontal application to vertical application possibilities.

The invention relates to cationic water-soluble polyelectrolytes, especially terpolymers, which are obtained by polymerising monomers of (meth)acrylamide, a quaternised (meth)acrylamide derivative, a (meth)acrylic acid derivative and/or hydrolysis-stable cationic monomers. The composition of the polyelectrolytes is characterised by a toxicity index formula Fi=(QTP&#x2212;2QME)/10&#x2266;1 wherein QTP represents the total cationic charge of the polymer and QME represents the charge part of the ester type monomer. The invention also relates to the production and use of said polyelectrolytes and water-in-water polymer dispersions which contain said polyelectrolytes.
