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 The materials are public information associated with operations that have been sold or terminated or are outdated.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.

The Engineering Polymers/Nylon Resins files series consists of newsletters, magazines, handbooks, brochures, flyers, reports, and memoranda that focus on nylon resin products and their development, quality improvements, applications, marketing, and sales. A nylon resin is a synthetic polymer--thermoplastic--that is a type of substance that becomes plastic upon heating and hardens upon cooling. These materials include information about various DuPont nylon resins: C12, Nylon 612, Nylon 1212, blow molding, Selar BR, and Zytel. The materials date between 1972 and 2006. This is the largest series in the collection.

The Engineering Polymers/Hytrel Polyester Elastomer files series contains reports, manuals, and memoranda that focus on the synthetic Hytrel, which is a thermoplastic elastomer (a type of polymer) that is elastic or rubbery. The Hytrel Polyester Operation was located at Chambers Works in Deepwater, New Jersey. There is documentation of the 3GT (trimethylene terephthalate) continuous polymerization line, a process to make the polymer above a certain quality in pellet form trial operation, successfully performed at Chambers Works in 1999. (Polymers can be formulated into pellets, granules, powder, and other polymeric materials during processing before reaching their end-stage applications.) The materials focus on process hazards analysis and safety for Hytrel and 3GT. Of particular interest are reports that outline the work plan to decontaminate, mothball, and tear down the Chambers Works facility. The plan was cited as best practice by the Engineering Polymers SHEA office, the corporate SHEA office, and the Chambers Works Dismantle & Demolish (D&D) group, in part because it addressed information management and security issues. This series dates from 1991 to 2000.

The Engineering Polymers improvement initiatives series consists of information about initiatives that were unique to the Engineering Polymers Division. These include workshops and procedures on initiatives, such as Balanced Scorecard-Based Managing Process, EP Strategies incorporating Six Sigma, and DuPont Performance Materials. The materials date from 1992 to 2011.

The DuPont corporate improvement initiatives files series documents DuPont's leadership strategies to improve operation performance and new product development through new methodologies developed by centralized groups. The materials include presentations, memoranda, reports, manuals and guides, workbooks, reports, newspaper or magazine clippings on initiatives to incorporate Six Sigma methodology, supply-chain management and operations, sales and operational planning, improved return on net assets, business development systems, quality and process control, and effectiveness. The materials date from 1980 to 2019.

The General files series consists of a variety of materials, such as additional newsletters documenting milestone anniversaries, acquisition strategies, and operations. There is a safety booklet dating from 1915, a document of sample DuPont chemical processes from 1991, and a history of Termbley Point dating from around 2009.
