Stephanie Kwolek begins the interview with a discussion of her early career at DuPont. She joined DuPont in 1946, the same year she earned her B.S. in chemistry at Carnegie-Mellon University. Kwolek spent much of her time working on polymers, including aliphatic and aromatic polyamides. She discusses her level of independence in the laboratory, as well as her relationship with her supervisors. Kwolek began work with 1,4-B and was able to get a high molecular weight polymer. It was eventually discovered that the polymer spun beautifully and was quite strong. This polymer became Kevlar. Kwolek describes industry competition, the testing and scale-up of Kevlar, and the problems of confidentiality. She further discusses the relationship between Kevlar and Paul Flory's theory of liquid polymer crystals. Kwolek concludes the interview with comments on her love of writing, her decision to leave DuPont, and the future of polymer research.
