Notes

Thomas EngelProfessor Engel is internationally known for his exceptional research in the production of polymers. In 1966, he developed a process for cross-linking plastic extrusions, particularly those of cross-linked polyethylene. Based on the reaction of plastics at pressures of 15'000 to 150'000 psi and temperatures of approximately 300°C., and in the presence of a peroxide catalyst, a cross-linking agent, this process was a significant step forward in plastics technology. It resulted in the production oa high molecular weight product having improved heat and chemical resistance, which is still in extensive use nearly thirty years later.Engel has received numerous prizes and honors for his work. In 1972, he was awarded the ?Diesel Prize? along with with Dr. Wernher von Braun, the rocket and space technologist.
