The Stretch of Genius: German Contributions to Nylon and Polymer Physics

If Staudinger provided the existence of polymers, (1899–1963) provided their mechanics. In the 1930s and 1940s, Kuhn, working at the University of Basel and later in Germany, developed the statistical mechanical model of polymer chains. He proposed the Kuhn segment —a hypothetical unit of a polymer chain that acts independently of its neighbors. This model allowed physicists to apply random walk statistics to long molecules. german nylonpics

During the 1930s and 1940s, German industry (I.G. Farben) developed its own synthetic fiber, (polyamide 6), independently of DuPont’s nylon 66. While Perlon used a different monomer (caprolactam), its production relied entirely on German physical principles: melt spinning, orientation drawing, and annealing. German physicists realized that drawing a nylon fiber (stretching it to several times its length) forces the polymer chains to align parallel to the fiber axis. This increases crystallinity, tensile strength, and modulus. The physics of strain-induced crystallization —a phenomenon first rigorously described in German laboratories—explains why a nylon fishing line is strong but a nylon stockinette is supple.
