The name "nylons" refers to the group of plastics known as 'polyamides'. Nylons are typified by amide groups CONH and encompass a range of material types e. Nylon 6,6; Nylon 6,12; Nylon 4,6; Nylon 6; Nylon 12 etc. Nylon is used in the production of film and fibre, but is also available as a moulding compound. Nylon is formed by two methods.

Nylons (Polyamide)

Nylon is a generic designation for a family of synthetic polymers composed of polyamides repeating units linked by amide links. Nylon polymers have found significant commercial applications in fabric and fibers apparel, flooring and rubber reinforcement , in shapes molded parts for cars, electrical equipment, etc. Nylon was the first commercially successful synthetic thermoplastic polymer. Nylon was first used commercially in a nylon- bristled toothbrush in , [5] [14] followed more famously in women's stockings or "nylons" which were shown at the New York World's Fair and first sold commercially in , [15] whereupon they became an instant commercial success with 64 million pairs sold during their first year on the market. During World War II, almost all nylon production was diverted to the military for use in parachutes and parachute cord. Wartime uses of nylon and other plastics greatly increased the market for the new materials.

Nylon-9 from unsaturated fatty derivatives: Preparation and characterization

Methyl azelaaldehydate, soy nitriles, and oleonitrile were compared as starting materials for making nylon Less difficulty was encountered in purifying intermediates from oleonitrile than from the other two. All 3 routes involved hydrolysis of methyl 9-aminononanoate to 9-aminononanoic acid. Self catalyzed hydrolysis of the amino ester in water produced low yields of monomer owing to oligomer formation, but hydrolysis in the presence of barium hydroxide was more successful.
