How is nylon 6 6 prepared
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 ... Web30 mrt. 2024 · 1. During one of the methods of polymerization: Nylon 6,6 is prepared from polycondensation of hexamethylene diamine (HMD) and adipic acid. The repeat unit of the polymer is − [ N H ( C H X 2) X 6 N H C O ( C H X 2) X 4 C O]. The diamine, which melts at 40.87 °C, is normally used in the form of a concentrated aqueous solution.
