Question

monomer of bristles of brushes which areplastic

Answer 1

The bristles of brushes are made of a polymeric plastic known as Nylon. It was a compound invented by the scientists of New York (NY) and London (LON) and was the first of its kind. Nylon is known for its strength and durability.

Initially, brushes were made from animal fur or hair. However, with the advent of nylon, a softer yet more durable material could be used for various purposes. Nylon became so popular that it was considered the most profitable material during the world wars. Nylon was commonly used in ropes and parachutes during both the wars.

Answer 2

Answer:

The monomer units of the plastic which is mainly used in the manufacturing of bristles of brush are adipic acid and hexamethylene diamine.  

Explanation:

These monomer units combine through condensation polymerization that leads to formation of Nylon-6,6 as the polymer. It is quite stable and unreactive polymer so it is safe for manufacturing of bristles of brush.  

Here the monomer units adipic acid and hexamethylene diamine combine through their functional group and $\bold{\mathrm{H}_{2} \mathrm{O}}$ will come out to form Nylon-6,6 polymer.
