Write the reactions for the formation of nylon 6, 6 polymer.
उत्तर
Preparation of nylon 6, 6:
- Nylon 6, 6 is obtained by polymerization reaction between the monomers adipic acid and hexamethylenediamine.
- Mixing of the two monomers forms nylon salt, which upon condensation polymerization under conditions of high temperature and pressure give the polyamide fibre, nylon 6, 6.
