उत्तर
- Nylon 6, 6 is obtained by a polymerisation 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, gives the polyamide fibre nylon 6, 6.
Notes
Student should refer to the answer according to their questions.
