Question

Identify linear polymer from following

• A. Nylon
• B. Poly-vinyl chloride (PVC)
• C. High-density polyethylene (HDPE), and polystyrene
• D. None of these

Hint:

Linear polymers like Nylon are characterized by straight chains, whereas addition polymers like PVC have branched or network structures.

Answer 1

The Correct Option is A

The correct answer is Nylon.

Explanation:

• Nylon: Nylon is a synthetic polymer that is classified as a linear polymer. Linear polymers consist of long chains of repeating monomer units, where the monomers are connected end-to-end in a straight line. In the case of nylon, the repeating monomer unit is derived from diamines and dicarboxylic acids, which form long, continuous chains during the polymerization process.
• Polymer Structure: Nylon, specifically Nylon-6,6 (a common type), is formed by the condensation polymerization of hexamethylenediamine and adipic acid. This results in a linear polymer structure, meaning that the polymer chains are not branched or crosslinked.
• Properties of Linear Polymers: Linear polymers like nylon have high tensile strength, making them suitable for use in textiles, ropes, and industrial applications. The linear arrangement of the polymer chains allows for strong intermolecular forces, such as hydrogen bonding, contributing to nylon's strength and durability.

Other Types of Polymers:

• Branched Polymers: These polymers have side chains branching off the main chain, which can impact their physical properties, such as lower density and flexibility.
• Crosslinked Polymers: These polymers have chains that are chemically linked to each other at certain points, forming a network. This structure gives them greater rigidity and heat resistance compared to linear polymers.

Nylon's linear structure makes it highly suitable for products that require strength and resistance to wear and tear, such as clothing, automotive parts, and industrial materials.
