Question

Write the names of the monomers of the following polymers such as bakelite and nylon-$6,6$.

Answer 1

Bakelite:

• Monomers involved are phenol $\left({\mathrm{C}}_6{\mathrm{H}}_6\mathrm{O}\right)$ and formaldehyde $\left(\mathrm{HCHO}\right)$.
• Bakelite is also referred to as thermosetting phenol formaldehyde resin.

Nylon-$6,6$

• Monomers involved are adipic acid $\left(\mathrm{HOOC}-{\left({\mathrm{CH}}_2\right)}_4-\mathrm{COOH}\right)$ and hexamethylenediamine $\left({\mathrm{H}}_2\mathrm{N}-{\left({\mathrm{CH}}_2\right)}_6-{\mathrm{NH}}_2\right)$.
• Nylon-$6,6$ is a polyamide.
