Title: Walter K Homann: Innovator in Polyester Technology
Introduction
Walter K Homann is a notable inventor based in Dulmen, Germany. He has made significant contributions to the field of polymer chemistry, particularly in the development of high-molecular-weight polyesters. With a total of seven patents to his name, his work has had a lasting impact on the industry.
Latest Patents
Homann's latest patents include innovative processes for preparing high-molecular-weight polyesters. One of his patents describes a method for polycondensing an aromatic dicarboxylic acid with a mixture of alkanediols and alkenediols. This process is conducted with substantial exclusion of oxygen and in the presence of a catalyst, achieving a viscosity number in the range from 50 to 140 cm³/g. The material is then postcondensed in the solid phase until the desired viscosity is reached. Another patent outlines a method for quickly obtaining high-molecular-weight polyesters by incorporating proportions of an alkene diol. This polyester undergoes a treatment with ionizing radiation to achieve the required viscosity number, allowing for the production of polyesters with specific property profiles.
