NCERT Grade 12 Chemistry Chapter 15, Polymers deals with introduction, classification, structure, function and application of polymers. The study of polymers is essential as polymers are the backbone of four major industries viz. plastics, elastomers, fibres and paints and varnishes. After studying this chapter, students will be able to explain the terms - monomer, polymer and polymerisation and appreciate their importance; distinguish between various classes of polymers and different types of polymerisation processes; appreciate the formation of polymers from mono- and bifunctional monomer molecules; describe the preparation of some important synthetic polymers and their properties and appreciate the importance of polymers in daily life.
Classification of Polymers Based on Source, Structure of Polymers, Mode of Polymerisation, Molecular Forces, Growth Polymerisation; Types of Polymerisation Reactions, Addition Polymerisation or Chain Growth Polymerisation, Condensation Polymerisation or Step Growth polymerisation, Copolymerisation, Rubber, Molecular Mass of Polymers, Biodegradable Polymers and Polymers of Commercial Importance are the topics studied in this chapter. An important branch of organic chemistry, Polymers are used in the manufacture of plastic buckets, cups and saucers, children’s toys, packaging bags, synthetic clothing materials, automobile tyres, gears and seals, electrical insulating materials and machine parts has completely revolutionised the daily life as well as the industrial scenario and hence their study is important.
