First commercially available as a toothbrush (1938), Nylon is a thermoplastic material trademarked by what company?
Nylon was the first commercially successful synthetic thermoplastic polymer. DuPont began its research project in 1927. The first example of nylon (nylon 6,6) was produced using diamines on February 28, 1935, by Wallace Hume Carothers at DuPont's research facility at the DuPont Experimental Station. In response to Carothers' work, Paul Schlack at IG Farben developed nylon 6, a different molecule based on caprolactam, on January 29, 1938. Nylon was first used commercially in a nylon-bristled toothbrush in 1938, followed more famously in women's stockings or "nylons" which were shown at the 1939 New York World's Fair and first sold commercially in
Nylon 1,6 it is interesting that nylon 1,6 is a rare example of a polyamide thermoset resin rather than a thermoplastic material. Nylon 1,6 has been reported to exhibit a high moisture absorbance owing to the significant density of amide residues in the polymer, >130% of its weight (compare to ~2-2.5% for nylon 66 and nylon 6). Nylon 1,6 Nylon 1,6 (aka polyamide 1,6) is a type of polyamide or nylon. Unlike most other nylons, nylon 1,6 is not a condensation polymer, but instead is formed by an acid-catalyzed synthesis from adiponitrile, formaldehyde, and water. The material was produced and studied by
