Title: Fred R Feder: Innovator in Polymer Processing
Introduction
Fred R Feder is a notable inventor based in Collierville, TN (US). He has made significant contributions to the field of polymer processing, holding two patents that showcase his innovative approaches. His work has had a lasting impact on the industry, particularly in the methods of grinding soft polymers.
Latest Patents
Fred R Feder's latest patents include a "Process for removing the solvent from a polymer solution" and a "Process for ambient temperature grinding of soft polymers." The latter patent describes a method where soft and tacky polymers can be ground at ambient temperature using a grinding aid in an attrition mill. This mill features counter-rotating grinding elements that operate above a minimum tip speed of 170 m/sec and achieve a throughput of more than 90 kg/hr. The grinding aid, which can be either organic or inorganic, such as calcium carbonate, is used in an amount of about 5-20% based on the weight of the polymer. The mill temperature is carefully adjusted to retain nearly all of the grinding aid on the softened polymer particles, thereby improving polymer flow and minimizing the disposal of loose grinding aid. Additionally, air is drawn through the mill to serve as a material carrier medium and to cool the mill if necessary.
Career Highlights
Throughout his career, Fred R Feder has worked with prominent companies, including E.I. du Pont de Nemours and Company and Fina Research, S.A. His experience in these organizations has contributed to his expertise in polymer processing and innovation.
Collaborations
Fred has collaborated with notable coworkers such as Arthur W Opsahl and Kenneth N Yarbrough. Their combined efforts have further advanced the field of polymer technology.
Conclusion
Fred R Feder's contributions to polymer processing through his innovative patents and collaborations highlight his role as a significant inventor in the industry. His work continues to influence the methods used in polymer grinding and processing today.
