Schollenberger was hired at
B. F. Goodrich in 1947 by
Waldo Semon, helping to open a new research center in Brecksville, Ohio in 1948. In 1952, Schollenberger patented the first thermoplastic polyurethane. He continued developing the product until 1958 when the new material debuted under the trade name Estane. It is a strong, flexible, abrasion-resistant material that was used in textile coatings, tennis shoe soles, automobile parts, as well as
magnetic tape. Schollenberg was promoted to R&D Fellow - the highest research position at Goodrich in 1975. He was a prolific inventor, with 18 U.S. and 10 foreign patents. Schollenberger retired in 1984, when Estane accounted for roughly one third of specialty chemical sales at the company. ==Recognition==
