    Abstract: The invention relates to the synthesis of (meth)acrylate-based mass polymers which are soluble in aqueous alkaline. The invention in particular relates to the synthesis of polymers by means of a mass polymerization. Said mass polymers have a significantly improved solubility in aqueous alkaline media over corresponding polymers produced by means of a heterogeneous aqueous polymerization method, such as emulsion or suspension polymerization. Improved solubility in said context refers to the dissolution rate being faster among particles of equal size, to no significant turbidity remaining after dissolution and to the viscosity of the obtained solutions being lower at the identical ratio of solids content. Furthermore, the compatibility of the compounds according to the invention with water-based varnishes is at least comparable or even improved.

    Abstract: Aqueous liquid and moisture vapor are added to water absorbent resin powder so that particles of the water absorbent resin powder are bound. In forming bound particles by supplying aqueous liquid and moisture vapor to the water absorbent resin powder, the foregoing arrangement makes it possible to supply moisture to whole the powder so that a less amount of particles remains unbound (ungranulated) and increase of a concentration of the water absorbent resin bound particles allows for further improvement of a drying efficiency and makes it possible to obtain particulate water absorbent resin having excellent properties even when the bound particles are highly concentrated. The present invention provides (i) a method for binding water absorbent resin and (ii) a method for producing particulate water absorbent resin which method includes the step of binding particles of water absorbent resin powder. The foregoing effect can be obtained by these methods.

  • Publication number: 20110172314
    Abstract: The present invention relates to amphiphilic branched copolymers, methods for their preparation, emulsions comprising such copolymers and their use as emulsifiers. The polymers are responsive by nature, by forming non-covalent bonds between monomer residues upon applying external stimuli. In a preferred embodiment of the copolymer, the copolymer can be used to stabilise emulsions and the emulsion droplets can be reversibly aggregated and de-aggregated.
