Condensation polymerisation generally involves a repetitive condensation reaction between two bi-functional or trifunctional monomeric units. These polycondensation reactions may result in the loss of some simple molecules as water, alcohol, hydrogen chloride, etc., and lead to the formation of high molecular mass condensation polymers. In these reactions, the product of each step is again a bi-functional species and the sequence of condensation goes on. Since, each step produces a distinct functionalised species and is independent of each other, this process is also called as step growth polymerisation.

Which of the following polymer is known as Perlon L?

Nylon 6

The correct answer is option 2.Nylon-6.

Perlon L is a trade name for a specific type of nylon, which is Nylon 6. Nylon 6 is a synthetic polymer that is formed through the polymerization of caprolactam monomers. It's called Nylon 6 because each repeating unit in its polymer chain contains six carbon atoms.

Perlon L, being a brand name, is often used to denote Nylon 6 specifically. Nylon 6 has excellent mechanical properties, including high tensile strength, abrasion resistance, and elasticity, making it suitable for a wide range of applications. It's commonly used in the manufacturing of textiles, fibers, and engineering plastics.

So, in summary, Perlon L refers to Nylon 6, a type of nylon polymer known for its strength, durability, and versatility in various industrial and consumer applications.
