Nylon Nylon was discovered in 1935. The name nylon is derived from two cities where it was discovered namely New York (ny) and London (lon).
Nylon Nylon was discovered in 1935 and is a polymer which has repeated functional group of an amide. An amide unit is ---CO---NH---. This is the reason why nylon is called a polyamide. The name nylon is derived from two cities where it was discovered namely New York (ny) and London (lon). Preparation of nylon Nylon is made from dicarboxylic acid called adipic acid. Adipic acid is actually tetra methylene dicarboxylic acid. A diamine called hexamethylene diamine is added to adipic acid. The raw materials required for the manufacture of nylon are : Adipic acid of tetra methylene dicarboxylic acid Hexamethylene diamine Polymerization takes place and water along with a polyamide that is nylon is the end product. The reaction is shown below. The COOH or the carboxyl groups from the acid react with the NH2 or the amino group from the diamine to form an amide structure, which is a polymer. The number n shows that there are very large numbers of ---CO---NH---- groups. This is an amide structure hence the product is called a polyamide. The polyamide is forced through spinnerets to get threads of nylon. The polyamide can also be cast into different shapes by moulds.
