Title: Innovations by Johannes M Verheijen
Introduction
Johannes M Verheijen is a notable inventor based in Ranst, Belgium. He has made significant contributions to the field of polyester production, holding two patents that enhance the properties of this important material. His work focuses on improving the electroconductive and thermo-oxidative properties of polyesters, which are widely used in various applications.
Latest Patents
Verheijen's latest patents include a process for the production of polyester with increased electroconductive properties. This innovative method involves a continuous direct esterification and polycondensation process, where terephthalic acid and ethylene glycol are supplied to bis(betahydroxy ethyl) terephthalate or its oligomer. The process ensures that the electroconductivity enhancing additive, preferably a metallic salt like magnesium acetate, is added at the right moment to optimize the reaction.
Another significant patent by Verheijen is for a process that enhances the thermo-oxidative stability of polyester. This method also utilizes a continuous direct esterification and polycondensation process, where a stabilizing solution containing an aliphatic diol and phosphite is introduced before polycondensation begins. This innovation aims to improve the durability and performance of polyester in various applications.
