Patent: Polymers degradation during extrusion can now be quantified in real time

The patent, result of the doctoral programme developed by Ademar Tibola, a former Ph.D. student from the PPGCEM, discloses an in-line optical detector to monitor the polymer extrusion process consisting of a refrigerated set of two emitting sensors and a receiver, both operating in the near infrared range, NIR. Such a system detects thermomechanical degradation of polymers during extrusion but can also be used in thin-walled plastic products.

          At the end of November 2023, we were pleased to know the approval of the patent application BR 102022009461-6 A2, that reveals an in-line optical monitoring system, operating in the near infrared NIR, to quantify the thermomechanical degradation of polymers in real time during the process extrusion. It was filled on 16/05/2022 at the National Institute of Intellectual Property INPI and published on 11/28/2023, record time, just 1.5 years after his submission, the result of the doctoral programme developed by Ademar Tibola, professor at the Communitary University of Chapecó, UNOCHAPECÓ. Tibola was a student at the UFSCar Graduate Science and Engineering Program, PPGCEM, being one of those enrolled in the Interinstitutional Doctoral Program, DINTER, led by UFSCar to the formation of researchers of UNOCHAPECÓ teachers, with approval and sponsorship of CAPES. His advisors were Prof. Sebastião V. Canevarolo of UFSCar/PPGCEM and Prof. Márcio Antônio Fiori, from the Graduate Program in Technology and Innovation Management-PPGTI of UNOCHAPECÓ. This result proves the close interrelationship between science and technology developed by researchers and their students in the two graduate programs, PPGCEM and PPGTI.
