Points to Remember
Some of the important points to remember from the NCERT Solutions for Class 12 Chemistry Chapter 15 are as follows:
The word ‘polymer’ is coined from two Greek words; ‘poly’ means many and ‘mer’ means unit or part.
The term polymer is defined as huge molecules having high molecular mass.
These are also called macromolecules, formed by joining repeating structural units on a large scale.
Therefore, the various applications depend upon their unique mechanical properties like tensile strength, elasticity, etc.
These mechanical properties are governed by intermolecular forces, e.g., Van Der Waals forces and hydrogen bonds present in the polymer.
The forces also bind the polymer chains.
Therefore, polymers are classified into four sub-groups based on the magnitude of their intermolecular forces.

Few Important Questions
What are the different types of ‘Polymers’?
Polymers can be classified into four main categories: thermoplastics, thermosets, elastomers, and synthetic fibers
What are the different types of ‘Natural Polymers’?
Some naturally occurring polymers are silk, wool, DNA, cellulose, and proteins.
What is the definition of ‘Polymerization reaction’?
Any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule is called a polymer. This process is called ‘Polymerization’.
