Klaus Walther is a notable inventor based in Marl, Germany. He has made significant contributions to the field of aqueous plastic dispersions, holding 2 patents that showcase his innovative approaches to polymerization processes.

Latest Patents

His latest patents include a "Process for the preparation of large-particle, aqueous plastic." This invention provides a method for creating large-particle, aqueous plastic dispersions, allowing for targeted adjustments of particle size. The process involves polymerizing a monomer in the presence of an anionic emulsifier, a non-branched, nonionic, water-soluble polymer auxiliary, and alkali metal or ammonium ions not bonded to the emulsifier. The polymer auxiliary is reproducibly prepared to ensure its agglomerating effect. Another significant patent is the "Process for the preparation of coarse, aqueous plastic dispersions." This method utilizes emulsion polymerization of free-radical-polymerizable monomers with a branched poly(ethylene oxide) and specific amounts of alkali metal and ammonium ions. This process effectively controls particle size and produces carboxylated rubber dispersions suitable for coating materials.
