WebNylon-6,6 is made by polymerising hexanedioic acid and 1,6-diaminohexane exactly as shown further up the page. Because the acid is acidic and the amine is basic, they first react together to form a salt. That is then converted into nylon-6,6 by heating it under pressure at 350°C. The two monomers can both be made from cyclohexane. WebNylon 66 is made of two monomers each containing 6 carbon atoms, hexamethylenediamine and adipic acid, which give nylon 66 its name. Aside from its …
WebCondensation polymerization is a chemical reaction in which monomeric units are chemically bonded by the removal of water. The formation of Nylon-6,6 is an example of condensation polymerization. In this reaction, Hexamethylenediamine reacts with adipic acid to give Nylon-6,6. n HOOC − ( CH 2) 4 − COOH Adipic Acid + n H 2 N − ( CH 2) 6 ... Web10 apr. 2024 · Nylon 6, 6, made up of monomer units hexamethylenediamine and adipic acid is the most common variant of this synthetic fibre. Each monomer is present alternately in the copolymer forming the repeating unit and each contributing six carbon atoms to the polymer chain. The final nylon structure is the result of the following reaction:
