  • Publication number: 20220049028
    Abstract: 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.

  • Publication number: 20220033540
    Abstract: Methods for producing final polymer A are provided that comprise the following steps: (A) providing a starting polymer V, the starting polymer V being obtainable by radical polymerization of the monomers (i), (ii), (iii), and (iv) as described herein in the amounts provided herein; and (B) hydrolyzing the provided starting polymer V under alkaline conditions to obtain the final polymer A, wherein the N—C(?O)R1 groups of formula (I) at least partially hydrolyze the monomers (i) polymerized into the starting polymer V to form primary amino groups. Certain final polymers A obtained are useful for a method for producing paper or cardboard comprising adding certain final polymers A to a first aqueous pulp suspension, dewatering the obtained second aqueous pulp suspension containing certain final polymers A on a water-permeable substrate to a wet paper structure, and further dewatering of the wet paper structure into a paper or cardboard.

  • Publication number: 20210123899
    Abstract: The present invention relates to a method for determining a concentration of a scale inhibitor in a salt water comprising an analysis with a calcium/magnesium ionselective electrode of a dialyzed first sample of the salt water, and a dialyzed second sample of the salt water which was supplemented with a known concentration of the scale inhibitor. The invention further relates to a method for inhibiting incrustation in a plant which contains a salt water comprising the steps of adding a scale inhibitor to the salt water at a desired concentration, determining the actual concentration of the scale inhibitor in the salt water as above, and adding further scale inhibitor to the salt water to adjust the desired concentration.
