Chemistry Revision Notes for Class 12 Chapter 15 Polymers

Chemistry chapters like Polymers might be little confusing to remember in one go, and hence revision is the best way to keep yourself through with the topics. Here we have discussed revision notes for chapter 15 – Polymers.

Classification of polymers based on source:

  • Natural polymers – Some examples are cellulose, rubber
  • Semi-synthetic polymers – Cellulose derivatives such as cellulose nitrate and cellulose acetate etc.
  • Synthetic polymers – Some examples are polythene, Buna – S, etc.

Classification of polymers based on the structure:

  • Linear polymers
  • Branched-chain polymers
  • Network polymers or Crosslinked

Classification of polymers based on the mode of polymerization:

  • Addition polymers
  • Condensation polymers

Based on the molecular forces polymers are classified into:

  • Elastomers
  • Fibers
  • Thermoplastic polymers
  • Thermosetting polymers

To gain in-depth knowledge of various classes of polymers, polymerization processes, and their preparation process, etc.

Frequently asked Questions on CBSE Class 12 Chemistry Notes Chapter 15: Polymers


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’.
