Title: The Innovations of Hans Joachim Leugering

Introduction

Hans Joachim Leugering is a notable inventor based in Frankfurt, Germany. He has made significant contributions to the field of polymer science, particularly in the development of oxymethylene polymers. With a total of 4 patents to his name, Leugering's work has had a substantial impact on engineering plastics.

Latest Patents

Leugering's latest patents include a process for preparing oxymethylene polymers in a granular form. This innovative method involves cooling a solution or dispersion of an oxymethylene polymer, which is initially above the sintering temperature, to just below that temperature. The process utilizes a mixture of methanol and water, with a methanol content of at least 75% by weight, as both the dissolving agent and the cooling agent. The resulting oxymethylene polymer is suitable for use as engineering plastic in the production of molded articles. Another significant patent is for the manufacture of granular oxymethylene polymers, where the cooling occurs in two stages, again using a methanol/water mixture. This granular POM is also suitable as a technical material for creating shaped articles.
