Title: The Innovations of Petrus H Schreurs
Introduction
Petrus H Schreurs is a notable inventor based in Deventer, Netherlands. He has made significant contributions to the field of polymer chemistry, particularly in the area of vinyl chloride polymerization. With a total of 2 patents, Schreurs has demonstrated his expertise and innovative spirit in developing new processes and compositions.
Latest Patents
One of Schreurs' latest patents is titled "Process for the suspension (CO)polymerization of vinyl chloride." This invention discloses an improved method for the suspension polymerization of vinyl chloride using a radical initiator and at least two suspension stabilizers. The process involves the use of a primary stabilizer, which can be a water-soluble partially hydrolyzed polyvinyl acetate or methyl hydroxypropyl cellulose, along with a secondary stabilizer from the group of N-alkyl gluconamides, where the alkyl group contains between 16 to 20 carbon atoms.
Another significant patent is for a "Concentrated aqueous metal aldonate and/or ammonium aldonate composition." This invention relates to a concentrated aqueous composition where part of the aldonate is dissolved and part is suspended in water. Sodium gluconate is preferred in this composition, which also includes a colloidally dispersed gum as a suspending agent. Gums with carboxyl groups, such as xanthan gum, are particularly effective in creating stable compositions with a high aldonate content. These compositions have various applications, including use in cleansing preparations for glass and metal surfaces, etching aluminum, galvanizing processes, leather tanning, paper making, textile treatment, paint removers, photography fixing baths, and agricultural and pharmaceutical preparations.
