JEE Advanced Chemistry Polymers – Classification, Polymerization & Applications

Polymers are high molecular mass compounds formed by the repeated joining of small molecules called monomers. They are widely used in everyday life and industrial applications due to their versatility and durability.

This chapter is important for JEE Advanced Chemistry and frequently appears in conceptual questions.

What are Polymers?

Polymers are macromolecules consisting of a large number of repeating structural units linked together through chemical bonds.

Important Concepts

Monomers and Polymerization

Monomers are small molecules that combine to form polymers through a process known as polymerization.

Types of Polymerization

Addition Polymerization

In addition polymerization, monomers combine without the elimination of any small molecule.

Condensation Polymerization

In condensation polymerization, monomers combine with the elimination of small molecules such as water or hydrogen chloride.

Classification of Polymers

Polymers can be classified as:

Natural Polymers
Synthetic Polymers
Addition Polymers
Condensation Polymers
Biodegradable Polymers

Important Polymers

Some commonly used polymers include:

Polythene
PVC
Nylon
Bakelite
Teflon
Polyester

Applications
