John M. Barineau (1950-) worked at the DuPont Company for more than forty-five years, serving in a variety of capacities, including operations, product and process development, quality management, product management, capital project management, process safety management, Six Sigma improvements of supply chains, and purchasing, as well as with customers and suppliers working at or visiting approximately seventy DuPont Company sites and contract operations in sixteen countries. E.I. du Pont de Nemours & Company is a chemical company more commonly referred to as the DuPont company. This small collection of Barineau's papers provides insight into product development. The materials are public information associated with operations that have been sold or terminated or are outdated. These documents show a "behind-the-scenes" view of what was happening within DuPont. The collection has been arranged into five series: Engineering Polymers/Nylon Resins files, Engineering Polymers/Hytrel Polyester Elastomer files, Engineering Polymers improvement initiatives files, DuPont corporate improvement initiatives files, and General files.
