With a total of three patents to his name, De Cleyn's work has advanced the production processes and applications of optical data carriers.
Latest Patents
One of De Cleyn's latest patents is titled "Device and method for degassing solvent-containing polycarbonate solutions." This invention relates to an apparatus and a process for devolatilizing solvent-containing polycarbonate solutions. By employing this innovative apparatus, polycarbonates with low residual values of volatile constituents are produced from solvent-containing polymer melts. This process improves optical properties, especially the yellowness index, through a combination of a heatable tubular devolatilizer and a vented extruder. Another significant patent is "Optical data carriers and method for producing the same." This patent discloses a process for preparing optical data carriers made from a specific polycarbonate. The polycarbonate is produced using a phase boundary process that involves reacting dihydroxydiarylalkane in the form of its alkali metal salts with phosgene in a heterogeneous phase. The process is characterized by a low content of certain metals and the separation of the organic solvent, resulting in a polycarbonate that is particularly useful for optical data carriers.
