Title: Heribert J Macherey: Innovator in Wet Strength Agents and Lubricant Compositions
Introduction
Heribert J Macherey is a notable inventor based in Kreuzau, Germany. He has made significant contributions to the field of chemical engineering, particularly in the development of wet strength agents and lubricant compositions. With a total of 2 patents to his name, Macherey's work has had a considerable impact on various industrial applications.
Latest Patents
Macherey's latest patents include a method for producing a wet strength agent. This innovative method involves several steps, starting with the reaction of a nitrogen-containing polymer with a hydrophobic compound. This process creates hydrophobic side-chain substituents on the polymer. The second step involves reacting the hydrophobised nitrogen-containing polymer with a crosslinker to form a cationic nitrogen-containing resin. The final step includes the formation of particles through emulsion polymerisation of ethylenically unsaturated monomers in the presence of the wet strength resin. This invention is particularly relevant for use in cellulosic suspensions and the production of tissue paper.
Another significant patent by Macherey focuses on compositions derived from α,β-unsaturated dicarboxylic acid esters. This composition comprises the reaction product of specific unsaturated dicarboxylic acid esters and olefinically unsaturated compounds. The resulting product is characterized by an intermediate molecular weight reaction product, which is distinct from known lower molecular weight alkenyl or alkyl succinic reaction products. These compositions are especially suitable for use as lubricants and lubricant additives.
